I have the tendency to wonder about different scenarios regarding if my boy friend were to encounter girls from his past that he's had history with. I get so caught up in these scenarios and sometimes lose sight of reality and what's actually happening right now. Most of the time, I end up feeling insecure and out of place. It's extremely frustrating and this way of thinking sometimes emerges small problems between him and I because I'm convinced these hypotheticals will happen. I'm an idiot.

Has anyone else found themselves in a similar situation and if you were able to improve your way of thinking, what would you suggest for me and possibly others? Thank you!
