Re: Should I Tell?

Hi,

I need an answer to this as soon as possible please if you can help.

I guy i was seeing, its complicated....but anyway 9 months ago he found someone who lived nearer to him, so decided we should stop seeing each other. Anyway i asked to talk a few weeks after, he agreed and to my suprise asked me up on valentines day, he was very nice and spoke about when we first met.I went to his house feelings were definately still there but i felt hurt, thing is im almost sure something wouldve happened had i not closed up and we ended up arguing, so i went home.
He was still with this girl at the time and even though we argued that night after a few weeks we remained on good terms
anyway a month or so ago, his girlfriend went on holiday back home(asia) and we started chatting again, hed ask how i was getting on with college applications(i was planning on moving to the city where he lived for a course, it was the only place the course was so i had to).....
anyway he regurly texted me on how i was and i replied, it was nice, kinda like old times....then i went up for an interview for my college app. and stayed in a hotel.
i mentioned this to him and he text me back asking where i was staying and if i was alone.
he asked if i wanted him to say hi so i said yes.
he came to my room that night and i really thought he was just being friendly, although i wanted something to happen i didnt expect it to.
But he started hugging me and kissing me and i resisted at first but i gave in to my feelings, nothing serious happened but things did happen.
He said not to mention it to anyone and then i realised his girlfriend was coming home a day or two after..
We didnt talk for awhile after that but when i contacted him 2 weeks after, he told me he was fine and was getting married.
I was upset and asked all the questions youd expect, i angered him i guess, he told me he came to see me in the hotel to make sure he didnt want to be with me before he chose to get married. Thing is he couldve done that without being all over me. I know he doesnt love me but i know he still has feelings for me.
I dont know, should i tell his girlfriend before she marries him, she doesnt believe in sex until after marriage and this is important to her( it seems odd hes getting married so soon to her, i reckon its the no pre-marital sex because hes not the rush into marriage type).
He's had doubts and hes lied, he says he loves her but i dont think he really does the way she needs. Its not fair on her.
If i tell her and she breaks up with him, itll be right thing for her in the end but he'll hate me and may not speak to me again but then again after awhile may come round.
If i dont tell her theyll get married, for probably all the wrong reasons and break my heart.
Then, if i tell her and she doesnt really believe me, and trusts what he says, theyll get married, hell hate me and wont speak to me definately ever again.

I really dont know what to do, can you help?
