I appreciate and take all the blame some people put on me and the praises as well. I also want to let you know that i will accept all your swear words too. But one thing is i never though my own wife will hide such pregnancy away from me and who on earth would tell me my wife is pregnant for me to believe because I trusted her so much. Though, she claimed she missed her period after one week of her stay which I quickly believe so sad.

Sorry for not repying on time as your responses are all meaningful to me and some took minutes to digest but
1, I dont want  to distroy the innocent child
I dont want a complicated life as it took nearly all my saving and time to bring her and if u know what it is with experience.
2, All female nairalanders  except deep soul, have been saying forgive and forget, easy to decide but will be hard to live with.
3, some people believe its a nigerian story. lucky you
4, if I leave her i will never love anyone again.
5, if I accept her I will live everyday of my life to remember this
6, I currently accept her temporarily and do not mant to rush into conclusion
7, she has got a good and reliable family.
8 WHATEVER THE  DECISION I MAKE I WILL LOSE because even forgiving her will create a huge hole in my heart likewise a divorce.
9, my deduction from your responses, she intentionally brought this to join me in the state.
10, so many questions on my mindlike you can think of, why?

Thanks for all your comments and advice, they are making sense to me and I have short period to make this decision please. Its matter of life, death, family and culture.
I initially thought this would be too much for nairalanders as I have been reading others story on nairaland and never thought I would become a part of such statistic.
Thank you all once more.

I am a young man in my late 20s, who struggled to get all I could to be a man and promised never to hurt my wife in no form.
I dated wife for two yrs before marriage. she was a very caring girl friend, loved by every member of my family before and after the marriage.
TROUBLE:
I left the country to further my studies in America while my wife was pregnant for me but she lost it while I was in the state after four months trying
to get her to join me. I tried harder for her visa because of her situation and always come back after each exams to see her.
She eventually got the entry visa to join me. Meanwhile the last visit was 10 months before she joined me as we were sure she would be joining soon but
due to some delays at the embassy. All along I was giving her the same salary monthly like in her office.
SURPRISE:
My wife was already over 5months pregant when she joined me. I never noticed this but got to know after two months with me (making it seven months) when we
visited a doctor for a pregnancy test. The scan revealed its 30 weeks (seven and half months)old. This means she got pregnant for someone else within the that
period we were apart. I didn't do anything in the hospital but got home to discuss the meaning of the period and its implications.
She denied all this that she doesn't understand but later confessed it was a night party with her friends from the office that made her have sex with a guy
she met at the party. she got to realise she was pregnant only when she was coming to join me. All the was slap her twice and realised it wont solve
solve the problem. I walked out of the house for some hours and when I came back I found a letter which
Read's Dear boyzone, I deeply regret my action and will like you to find a place in your hearth to forgive me. You have done nothing to deserve this.
May God provide you a good wife that will not bring shame to you and her family
I quickly called her and she came back to the house later. I asked where she was heading as she doesn't know anyone here and she said she wanted to kill her self
and at this point she already took some drugs with spirits to terminate the pregnancy and also kill herself if possible. In minutes she started feeling the pains in
her stomach from the effect of the drugs. I took her to the hospital again and was quickly treated and told to be admitted.

ADVICE:
Your advise is urgently needed. Feel free to advise me if I'm wrong at any point as well.
