So guys here it goes…it all started somewhere in October 2010, I was working in a MNC where I liked a girl. We have a common friend and I told him that I like her. She stole my mobile number form friends phone and called me later that night and we had a wonderful chat for half n hour and decided we should go out. Everything went fine and after coupling of meeting outside and in office for few months we were in a relationship. I forgot to tell I am 24 and she is 20.
Trouble started when she asked me to come on a adventure trip. Everything was great and we were all set to spend a night together that went worst night of my life, she told me that our common friend kissed her and she kissed him back. She started crying and saying sorry etc. I asked her that does she has any sort of feeling for him or she likes him, she said “ I don’t know”. I said to her that mistakes happen and if she loves me everything gonna be alright. Next day we are set to come back home which will take approx 10 hrs of travel time. What hurts me the most is that she was very normal, there were no sign of being guilty like nothing happened. On few occasions she also ignored me. Few you love someone from your heart and she kind of cheats on you then it’s obvious to feel miserable. And the first question is WHY SHE TOLD ME ABOUT THIS INCIDENT…was she trying to be honest and truthful to me…I don’t know ?

Few days later I also asked her about her behavior and used to say that she want to forget that incient and it was a big mistake and to tell me was even bigger mistake because we had a fight couple of times. I tried to let it go and everything was normal again. In late april or mid may I noticed that slight change in her behavior towards me, she no longer wants to talk frequently and doesn’t even say that she loves me. I again asked her what’s wrong with her then she told me she got university exams and she in lot of tension and wants to concentrate for exams. Exam kicked off on 28 may and we were in touch through text messages. On 4th of june she told me that we don’t have a future together and she doesn’t feel the same way and doesn’t love me anymore and she broke up with me, I simply asked her why she all doing this 3 days prior to my birthday…she said she don’t know. When i started to ask questions and reason behind she told me that she doesn’t have a reason and will talk after exams which ended on 17 june. 3 days have gone past and I haven’t heard any reason from her. I tried to talk on phone but she is least interested. I also got to know despite her busy schedule she meet her ex-boyfriend on 28 may and was very happy to see him and they talked a lot and both have feeling for each other.

I need few advices how to go about this ?? What should I do…i still like her but more than that I doubt her. The only question is why she did this to me. Tell me guys what the solution…is she hiding something or she got some major problem that she is not sharing with me.

When a girl avoids the guy she had been dating, the most obvious reason can be that she is no longer interested in that guy. I am sorry it may sound a bit rude but this is the truth.
May be she kept a relationship with you to get over her ex, or may be she wanted to make her ex jealous. When her work was done, she ignored you.
The fact is, dude, you will have to forget her. She definitely does not deserve you or your love.
Dont contact her, dont try to act desperate to talk.
Forget everything, I know how difficult it might be, but this is what is good for you. If in future she comes back, regretting, its upon you to decide to accept her or not.
Try to forget her, do things that you like, dont think about her much. Go out with your friends and get over it soon.
Someone else might be patiently waiting for you, a more deserving girl, I hope. :)
