My boyfriend and I have been together a little over a year. He has many guy friends and girl friends and I don't have a problem with that at all. There is this one girl who he is particularly close to whom I have also became friends with. She is very flirty and dates a lot but I never have been threatened by her, I trust my boyfriend. I found out a few days ago that her and my boyfriend had a purely sexual relationship before him and I started dating, and that she didn't like me at first because I 'stole' him away from her. I can't help but look at her differently now and I am ashamed to say that I am slightly jealous of her and now feel threatened. Her and my boyfriend talk a lot still and hang out, sometimes when I'm not there. I have never thought twice about that until now. Now I find myself questioning if they are too close? She called him last night at two in the morning, she does that sometimes when she's been out drinking, but this time when she did it I was very annoyed. I started thinking about our entire relationship and about this girl and now I feel like I've been had. I don't like that they are close and I don't like that she calls him all the time so late and that he does it too. Am I justified in this thinking? I think maybe I'm paranoid now because I know that they used to sleep together and I wonder if they would again. They definitely flirt with one another but she does that with everyone and I never thought anything of it - until now.
I almost don't want her hanging out anymore or being around us because now I feel like she's trying to weasel her way back in. But at the same time she's been around the whole time we have been together, over a year, and I've dealt with it. I wish I never knew that background of their relationship.
Any thoughts? am I being unreasonable in my thinking?
