I'll try to make this short and to the point.
I have a suspicion that my boyfriend may have feelings for another person that he is hiding from me. It's more of an intuition than anything, but although I've tried, I can't seem to shake these bothersome feelings. I am only his second relationship; the girl I'm concerned about was his first - not just first relationship, but in almost everything else as well. They dated for a long time through middle school and high school, broke up, started hooking up again and then it ended when they went to different universities, although they periodically hooked up throughout the next summer as well (I met him his sophomore year in college).
Now, she also has a boyfriend, and he tells me that they are only friends. However, I do know that she has drunkenly confessed that he's the hottest guy she's ever seen in her life (quote) and that she wants him. I know that at parties that I'm not present at, they spend the majority/all of their time together, and even at parties that he brings me too, they still talk much more to each other than anyone else. I've also noticed that while at school, he only talks to her on nights that I'm not around (very few), he's usually the first to start the conversation, and even though I've brought up to him how uncomfortable I feel about them, their conversations usually revolve around visiting each other. He and I both know that she is the only person he knows at that school, and if he were to visit, he would be sleeping at her place. He also has not shared any of this information with me.
I'm pretty secure when it comes to things like this and I know that my boyfriend loves me, but I also can't help but feel that when you break up with someone and you mean it, you shouldn't have enough feelings lingering around to be able to consistently hook up with them so much time later - only to be put off by living in two different cities. Especially since so much changes through high school, it worries me that they were able to go through all that change together and still come out of just as attracted to each other. Even if it just a sexual attraction, it bothers me that it was once backed up by mutual emotional feelings; even if it was only high school.
What do you guys think?
