Here are the signs to know if you’re in a relationship with such a man, who doesn’t understand the concept of giving you any space at all.
1. Constant sweet talker: Post first date,
this man will sweet talk, but ‘always’. Yes,
that’s the first sign that he just can’t do
without you ever. If after the first few
dates, a man is constantly texting you
throughout the day, narrating to you that
he’s busy daydreaming about you, naming
his unborn kids with you, and is more than
willing to meet you every now and then
(embarrassing you outside your workplace
with that pretty bunch of flowers), well,
he’s just too desperate and clingy. Think
of it, either the man is just trying to get
hooked on, or he’s so in need of a woman.
2. Friends no more: Does he bail out his
friends for you? Well, at first this may
sound really sweet of him, who doesn’t
like a man who prioritises his date over his
friends. But if he’s the kinds who cancels
every single plan with his friend just for
you, that’s an initial Mr. Needy sign. Come
to think of it, he’s about to mould a
relationship with you where in he’s
convinced you he’s ok with lying all day on
that couch with you rather than being at
the bowling alley with friends (always, that
is). And soon, he’ll need you to do the
same.
3. Do this, not that: When the man starts
giving you ultimatums, he’s just started off
with being needy. Has he ever done that?
It starts from asking you to make a choice
between him and the things that you want
to do. Such a man should be avoided
before you lose your mind pleasing him by
the minute.
4. I need you too: He needs to be with you
when you are with your friends. Who
doesn’t like a little ‘we time’ with friends,
without the partner. But what when your
guy is more than adamant to be a part of
the girl gang, even if that means when
he’s uninvited. Imagine what you’d ever
feel if your friend got along a date when
you girlies are having that bonding time.
Wouldn’t you think, he can’t leave her
alone even once.
5. Let’s do this faster: Has he initiated
talks about sex, living in, marriage, baby
names already! Well, there he is, wants it
all at once, actually ‘needs it now’. He
needs you to the extent of not willing to
even wait for time to pass before he knows
you better.
6. On and on: He met you in the morning,
calls you in the afternoon to show interest
of wanting to meet you at night. Then
again the next morning…. This sequence
goes on in the life of a man who can’t do
without a woman. Whether he has a job,
has friends to count on is besides the
point, the only thing that you can decipher
here is that he needs a woman in his life.
7. Sly stalker: Is he always liking your
posts and pictures, posting comments and
you know he checks his social networking
page only to stalk your profile. Well, that’s
a man who just can’t do without you and
has you on his mind.

Well, no one is perfect. Those who didn't even show red flags during courtship end up spilling the beans in marriage.
If people could just be themselves at all times relationships will be alot more better.
