lafex: ASSALAM ALAEKUM
I am also experiencing similar issue and I understand how you are feeling. You serious prayer and patience.
it is highly forbiding in islam to make a decision not to marry. There are many hadiths that condemn such and I think the closest of them to your issue is quoted thus(I am sorry for not quoting it word for word)
'three men went to the prophet, the first said I will never get married, the second said I will never sleep at night because of prayer and the third said I will keep fasting everyday till I die. The prophet replied them that I am the best among human and I am married, sleep and wake up, and fast and break'.
So you have no reason to take a decision not to marry. If you feel giving up with her is better, that means that is not the type of wife you dreamt of. Then leave her and continue journey for searching a wife.
I PRAY THAT MAY ALMIGHTY GIVE US THE BEST OF WIFE
AMEEN

tbaba1234: Lanrexlan, I think you should refer more to scholarly sources, in sha Allah. Too often, we just state our views. Islamic jurispudence can be quite complex.

There are conditions in which marriage can even be haram upon a person. For instance, if a person is going to make the other person miserable.

There is a good lecture on this by sheikh Yasir Qadhi.

Maclatunji's response is more appropriate here.

maclatunji: Since this is a matter of Islamic Jurisprudence, I will not state my understanding on the matter. Rather, I will insha Allah post quotes from authorities on the matter.

lanrexlan: Muslims are encouraged to get married.According to the sayings of prophet Muhammad(pbuh).It is narrated on the authority of Anas bin Malik(May Allah be pleased with him):A group of three men came to the houses of the wives of the Prophet(pbuh) asking how the Prophet worshipped (Allah),and when they were informed about that,they considered their worship insufficient and said, "Where are we from the Prophet as his past and future sins have been forgiven."
Then one of them said, "I will offer the prayer throughout the night forever." The other said,"I will fast throughout the year and will not break my fast." The third said, "I will keep away from the women and will not marry forever."
Allah's Apostle came to them and said, "Are you the same people who said so-and-so? By Allah,I am more submissive to Allah and more afraid of Him than you;yet I fast and break my fast,I do sleep and I also marry women.So he who does not follow my tradition in religion,is not from me (not one of my followers)[Sahih Al Bukhari Volume 7,Book 62,Hadith Number 1]

Narrated 'Abdullah(May Allah be pleased with him):We were with the Prophet(pbuh) while we were young and had no wealth whatever.So Allah's Apostle(pbuh) said, "O young people! Whoever among you can marry,should marry because it helps him lower his gaze and guard his modesty (i.e. his private parts from committing illegal sexual intercourse etc.),and whoever is not able to marry,should fast as fasting diminishes his sexual power[Sahih Al-Bukhari,Volume 7,Book 62,Hadith Number 4]
According to Sufyân Ibn Uyaynah (May Allah have Mercy on him),he said:The most nimble of creatures still have need of a voice.The cleverest women still need to have a husband,and the cleverest man still needs to consult wise men.

Capt. JH Miller:
Assalam..
I am a young muslim brother, growing up I never gave much taught to marriage as I knew I wouldn't marry till I was much older, as I grew older I started to reason not to get married until I meet a luvly muslimah. She is no doubt what I have dreamt of in a wife and more, I was able to convince myself we were meant for each other and we will spend our lives together and forever both in this dunya and akhira. One of my best moment was when we agreed to choose each other when we meet in الجنة , insha Alla.h..
Recently, it started to fall apart and we fought so often. I tried my best, put my ego and pride aside just so it will work but it just is not. I am a very simple person and believe so much In اللَّه سُبْحَانَهُ وَتَعَالَى will, but in this case it has been so difficult for me to just let be what will be, I have just tried to fight and fight to make it work. Maybe because I believe if I should lose her I'll probably never look to get married and will never get married.
Now I have started to go back to my previous ideology, I know marriage is half of your deen and it completes it, but is it forbidden not to marry?

My plan is to adopt children إنْ شَآ ءَ اللّهُ

جَزَاكُمُ اللّهُ
NB__ its not that I don't believe .اللَّه سُبْحَانَهُ وَتَعَالَى will replace her with someone better.

elrony: Yes u must marry...the sacred book says so!!!!

xclusive43: And i Qoute
Sheikh Ahmad Kutty , a senior lecturer and
Islamic scholar at the Islamic Institute of
Toronto, Ontario, Canada, states:

“Although marriage is generally considered
a highly recommended act, yet from the
point of view of fiqh (Islamic jurisprudence)
—because of diverse circumstances—it can
readily fall into one of the four categories
listed below: Fard (obligatory) or mustahabb
(recommended) or haram (forbidden) or
simply halal (permitted).
1. Marriage is considered fard (obligatory)
if a person is so tormented by sexual desire
that he/she fears falling into the sin of
fornication. Since staying away from
fornication is obligatory, and since
marriage is the only avenue for legitimate
sexual satisfaction, it becomes obligatory on
such a person to get married. This is based
on the principle in jurisprudence that says:
“If an obligatory thing cannot be fulfilled
except by fulfilling another, then fulfilling
the latter becomes equally obligatory.”

2. If, however, he or she is not so tormented
by sexual desire, and, hence, there is no
fear of falling into sin, then it is highly
recommended to get married if one has the
means to do so. By doing so, one is fulfilling
one of the great Sunnahs of the Prophet
(peace and blessings be upon him), our
perfect role model.

3. If a person knows for certain that he or
she cannot fulfill the duties required in
marriage, and there is no fear of his/her
falling into sin, then it becomes haram for
such a person to get married. Islam forbids
us from doing injustice to another person;
this would definitely be the case if one were
to neglect his/her spousal duties.

4. If a person has no means to marry and
is, therefore, incapable of fulfilling his
spousal duties, but has strong desire, it is
permitted for him to get married—provided
he tries earnestly to seek an honest source
of living. Allah has promised to help such a
person. We must also add here a further note that the Muslim community has a duty
to assist such people until such time that
they become self-reliant.
If, however, no such measures are
available, and a person finds himself unable
to fulfill his spousal duties, he is advised to
curb his desires through the discipline of
fasting and other acts of sublimation.”
