“He says if he gets the opportunity for one the he will go do it.” So this is your EX-boyfriend you’re talking about, right? Because ain’t no fucking way your man can say that shit to your face and you’re ok with it. He’s basically told you he’s going to cheat on you when he can and ain’t shit you can say or do about it!
Nooo way you both have to 100% sure. Don't let him guilt trip you into doing it
