Someone asked why I was angry he talked to this girl. Well, he broke up with me and told me he would tell me if he talked to another girl or met someone else. I kept asking him cause I figured he would meet another girl as soon as we broke up. I just wanted him to be honest because he was supposed to be thinking about whether or not we would get back together. We talked the entire time we were broken up and we even had sex for the first time while we were broken up. The thing is I just found out that the day before we had sex he started talking to this girl cause someone told him she liked him after the one time she saw him. They never hung out, they only met once and she has a boyfriend. I had him call her cause he lied and told me he had her number because it was his friend's gf and that was the only way he could reach him and that he put the number in there before we broke up. Because I am very jealous and have trouble trusting anyone I always used to check his phone for numbers and never saw that so I new because of that and because of what number she was that it was recently put in. He continued to lie to me until I stole his phone to call her myself. He got very angry and that is how I knew he was angry cause if he was telling the truth he wouldn't of cared if I called her or not. He said he didn't tell me cause he knew I wouldn't get back with him. I probably wouldn't of been that mad if he was honest with me because I was completely honest with him and told him I was talking to another guy. He swears he is telling the entire story and finally called her and asked if they ever hooked up and she said no but he could of always told her to say that. I'm not sure whether to believe him or not just because I can't tell when he is lying until it usually blows up to be this huge thing. I really want to stay with him because things were fine except for that he neglected to tell me that and then lied about it.
