I got married 18months ago to my long time girlfriend whom I was dating for last 10years. We had few issues in past also regarding her behavior with other guys. To be honest I never minded any such things but sometimes I use to think that she gets too cozy with other guys. I was the one who approached her to date me and after few days she said yes. That was the best day of my life. I was flying in sky. And than few days later she accepted a proposal from our one more classmate. Obviously we had a fight. I cried a lot and than she told me that guy forced her to accept the proposal. I trusted her, biggest mistake of my life. Previously also she use to talk to some other guys on phone behind my back. I ignored everything and tried to built the relation once again  the second biggest mistake of my life. Meanwhile we completed our school studies and got admission in different colleges. Things started to change once again, like when we use to have sex she used to ask me "you people enjoy so much having sex" I use to think why she isn't specific . We both were beginners but she used to give expert advices, I thought she might have got this knowledge either by reading about it or by watching porn. I admit "stupid,idiot etc" are the words for me. I use find many sim and mobiles in her room but whenever I asked her she use to say" mommy got a new one or sister or father" every time I believed her after fighting for few minutes or days. One day one of our mutual friend told me that she is going to a farmhouse of one boy in her class, I was shattered. Few hours later she called me to pick her from her college by 8pm as she won't be able to catch her cab due to some very important college project. He dropped her she came and sat in my car, I asked her about farmhouse and that boy, instead of answering she started fighting with me. I thought I am overreacting and ended the chapter. Gradually a day came when we were supposed to get married. Now we both were working I was into my own business and she was working in a company a bit far from house. One day I found out from her messages that she was a big flirt with almost everyone she was in touch with. And there were so many chats regarding she and her friends use call male escorts for their birthday parties and everything one could imagine of. I asked her " she said to divorce me and will take a fat alimony from me and will also make me bear all the bad consequences". I don't fear any such thing but problem is we are going to have a baby in  few months and I don't want to spoil the moment. Once again I've to compromise and live with the pain. Her father was against our marriage, And is a big time psychopath with great links. I cannot go to him not my parents. It's so insulting that  I can't even share it with friends too. To be honest I am here because nobody knows me over here. I want to commit suicide. Any easy methods please?
