Okay so I met him in Facebook we chatted for like 2 to 3 months. We used to like each other. I thought he liked me too and I used to give him hints that I really really like him and he was so sweet to me. And one day I proposed him on Facebook
And he got surprised. He never told me about his x-gf even when I asked him because he said he doesn't even remember those moments. I said it was okay and slowly after my proposal he used to say that... he thinks he is also starting to fall in love with me. He used to call me jasmine and one day he suddenly he told that he wants to meet I was so stupid that I said yes.

So one Saturday... actually it was 16th June he came to my place. Nobody was in my home... except my brother. He came and he was like so sweet. We talked for half an hour then he said he wanted to pee so I showed him the toilet. After he came back from the toilet he said that why wasn't I doing anything. Then I said I don't have the guts. Then he asked whether he could hug me. I couldn't speak a word but he came and hugged me tight and kissed me. And we did a little bit of kissing and sucking stuff.
Whatever!

Then he came for 2 more days. The 3rd day he proposed me he said he loves me too. I was too happy. Then the next day... a guy on Facebook... who is in the same as his said that he saw my boyfriend with another girl in college. Also that my boyfriend is very flirty so I just asked my boyfriend that... was he with any other girl? His reply was that he doesn't think it's necessary for him to answer the question. He started to talk rudely with him. And then suddenly that other guy who told me about my boyfriend said he's really dirty.

So he gave me an account id and password of a girl. There I saw my boyfriend had written that he still loves his ex girlfriend and he can't have any love feelings for any other girl.
So I told my boyfriend about all this. He got very angry and at last he said I don't trust him, and he wants to end this relation. I was like... no please don't do this... I love you a lot. But he reacted totally rudely

He said he has forgotten his ex girlfriend... he just made up that story. I believed him... and I was ready to forgive him. But he said he can't take it anymore he has been insulted a lot. Even one of my friends tried to make him understand. But he didn't listen. Now here I am alone. I don't get it?

So guys what should I do now? I feel like I want to suicide.

I really need help. Please

I guess you ruined it by spying, accusing, not trusting or believing him, and believing what other people told you instead.
Even if some of it is true, it was all done out of jealousy, and jealousy ruins relationships.
I'm sorry you want to die now. Ask your friends to be with you and take you every where they go so you aren't alone.

Then isn't it just a misunderstanding?

I think he is a rat fink who was taking advantage of you and it's a lesson to learn.No matter how much you chat on line, you better know him in person for awhile before you get to the kissing and sucking stuff.

You never know what evil lurks in the heart of a stranger.
