My boyfriend always jokes about cheating on me. After he met my dad he told me that he would never dare to cheat on me because my dad is very big and muscly. He made this joke multiple times. He jokes about how if he ever cheated on me he would be very careful and I would never find out. He joked about this just a couple of days ago. It has happened a lot and it makes me feel kind of worried because I have never joked about cheating and would never do it either, it’s not funny to me and I don’t want to make my partner worried. His jokes makes me paranoid because my ex joked about it too, and I found out that he had been cheating on me the whole time. But I don’t know if it’s something to be worried about because i’m not scared that my boyfriend is talking to other girls now, but i’m scared that he eventually will because of how much he talks about it. Is it something to be worried about?
