Me and boyfriend have been together for a really long time. He’s only had one girlfriend before me and they only dated for 3 months, but I’m still in highschool with her and I constantly overthink they’re past relationship. I compare myself to her and wonder if he said the same things to her that he says to me, or if he still thinks about her. It’s all ridiculous, but I can’t help but compare myself to her. I’m not sure how to stop, but it’s killing me.
