Search Results: making me feel guilty

been together for a year and 3 months, we have lived together from the start and we get on very well, I think he is with me but I'm not sure. He is very very protective of me, like the whole time we have been together I have seen my friends only three times and he made me take pictures to prove where I was. Anyway, recently its been getting quite rocky, I found out he talks to girls quite a lot, girls he has had a past with, and he tells me I'm over reacting, I don't have his fb password but he has mine. one weekend he was meant to be going to my family bbq (he has never met my family so this was a really big deal) and he bailed, and met up with friends instead, I was so sad but he made me feel guilty for going on at him so I shut up. That night I stayed at my parents house leaving him at his and he told me he was just seeing a couple of friends (boys) and then his phone accidentally called me and I heard girls. I called him up and he denied it, so the next morning I go to his and I walk in his room and he's in bed with this girl called Dan, who is over here on holiday. He kicks me out of the house so he can go back to bed with her. I was in love with him so I got back with him bcoz he told me he just slept in the same bed as her, that nothing happened at all. A week later I find that he hasn't cut off comunication with her bcoz he has her number on his phone still and he has her on Facebook. He said he had her number for ages but she was here on holiday and I know she got a new sim because her friend told me. I tell my friend that I'm not sure if I'm making the right decision by staying with him and she asks around if he did anything with this Dan girl. My friend asks her best friend (who was also there with her boyfriend on the night I found him in bed with her) and she said yes they had sex, not the time I walked in but twice before. so I ask the girl and she said yes they did have sex, she could be lying because her best friend really hates me. help please help
