I have been dating this girl for about one month now, and for the sake of discussion we'll call her Sally. Sally ended a relationship with her former boyfriend, we'll call him Billy, a couple months ago. Sally and Billy dated for a few months and briefly broke up, then got back together for a few weeks only to break up again after Billy threatened to release some "sensitive data".
For background, we're still in school, and Billy and Sally have classes together, (I have none with either of them). When I asked why she broke up with him, Sally said that it was because she couldn't hang out with him anymore, due to the conditions on which their relationship ended the first time (parents were involved).
Back to now, Sally and Billy regularly talk and Billy often does favors for Sally. Billy still has feelings for Sally, and makes them known. Sally maintains she only has feelings for me, and I trust her.
It should be noted that I also regularly talk to a former girlfriend, but the difference is that after we broke up - we've both moved on to other people and have just become good friends, as the relationship ended on good terms.
I feel uncomfortable whenever Billy talks to Sally, and even more so when he does things for her. I'd like to believe this is purely because he still has feelings for her, and maybe I'm just being jealous and quite frankly, pathetic.
For relevance, the other day Billy hugged Sally and apologized for what happened, which I'm not even sure how I feel about.
I have mentioned to Sally on two seperate occasions that I don't feel comfortable with her talking to Billy, at least in the volume that they talk which is almost as much, or maybe even more than we talk. Of the two times I told her, she said that she was sorry and that she won't let Billy become that personal with her again, and I'm not sure what exactly that details as nothing (seemingly) changed.
So I guess what I'm asking is, am I just being clingy/jealous? And furthermore, is my relationship with my former girlfriend a reason to not complain?
