Title mostly explains it. Do I suck for losing interest in the current person I have been dating, because I found out that they slept with the same girl my ex cheated on me with? I live in kentucky, this girl lives in Michigan where my ex lives. It's weird that they know each other, it's through the music scene, should I tell him I feel this way, or just brush it off and tell him I'm not interested. This girl gave my ex hpv, I'm going to go get tested tomorrow. Don't want to be involved in this.
