I have been dating this guy for the past 4 months. We have been to the same school and have a common set of friends but we never knew each other in school. We meet when I was travelling through europe. He was single when we met, he had been dating this girl for 2 yrs who he got pregnant within the first 4 months they were dating. When I met him we hit it off instantly and over time our visits got more frequent and soon I was living with him and everything seemed perfect. All this while he was in touch with his ex girlfriend as he said he had a responsibility towards her as he got her pregnant and she is going through a really tough time with her mother dying of cancer and he helps her out financially for her mothers treatment and I am OK with that. He said he just did not want to be with her because she takes up a lot of his energy and is not stable. 2 weeks back she came to visit him at his place and started a confrontation and asked him to confess to me that he had been sleeping with her the same time he was dating me. First he denied it but then later he confessed that he had slept with her twice first 9 days after we met and the second time a bit later. I was ready to forgive him but he said he needs a transition period for her to go back to her own country so that she is completely out of his life and for him to be alone for a while before he starts dating again. We broke up of course since I felt hurt and cheated upon and was very angry at the moment. He said we could be friends and I was very angry so I told him I never wanted to see him again or have any contact with him. 2 days back his ex girlfriend contacts me saying that she needs to tell me something very important( frm his fone and when I called back she/he never picked up the fone) and I called up his sister (angry) telling her to tell him not to contact me anymore... then I mssgd him to call me back and give me an explanation for what had happened but I got no response... the thing is I want to be with him and still date him... I miss him ever so much and I sincerely believe that this was meant to be. What should I do?
