My boyfriend said a girl added him on facebook and they started talking. Friday after he and I saw eachother and after I got back to my house we were texing and he gave me her number and he said that the girl he met wanted to talk to me. So I sent the girl a text and then she asked if I wanted to go on a double date next weekend with her and her boyfriend to see a movie, I agreed and I actually liked the idea. I was texting my boyfriend earlier today and we talk every day regardless if we hang out that day or not we always text and he had mentioned to me earlier that he was planning on going to one of his guy friend's house. A couple hours after he mentioned that we were talking about other stuff and then all the sudden he didn't reply to a simple text I had sent and it had been an hour late rwithout a reply and the girl he met on facebook texted me and said "guess who's next to me?" and I asked who and she said my boyfriend's name. At this point I was kind of mad because not only did my boyfriend stop texting me out of nowhere (because he never does that) but he went over to another girl's house who he has never even personally met before. Prior to today I didn't even know that my boyfriend had never met this girl personally and that she was a year younger and doesn't even go to our school (which is when I asked my boyfriend how he met her and he said through facebook). But I then texted my boyfriend saying I didn't know he was going over her house and he told me that his guy friend had other plans so he just decided to go to this girl's house. He told me they watched sci fi movies and he was probably there for only a couple hours. But it made me feel a little uneasy. This girl has been texting me and we've had a few short random conversations since Friday. She seems nice and it seems like she's trying to get to know me and not just my boyfriend and she is also in a relationship right now also so it makes me feel a little better about it all. I know he's going to hang out with other people aside from myself and he can't be with me 24/7 and it's selfish to say that he can't hang out with anyone else but it's just the circumstances of how he met her and how he went over there and how he didn't tell me that I thought were a little weird.
I am kind of angry about what happened but I feel as if I really shouldn't be but I can't help it! He doesn't have many close friends so I suppose he wants to meet some new people. But the thing is that I have only a few good friends and I wouldn't mind making more friends but I would never meet random people from facebook let alone random other men because I am already in a relationship! And I actually explained that to my boyfriend too and maybe he doesn't see it in the way that I do. I know I should trust my boyfriend but it's still getting to me. He always says he loves me and could never hurt me but I just care about him and I don't want to loose him or have my heart broken. Maybe I'm just being a bit insecure? What's your advice?
