Currently I’m with my boyfriend of two years and we had a bad break up like a few months ago, when we broke up I found him following another girl and liking her posts, so I assumed they were talking so I went a fucked around with a guy and we didn’t have sex but he gave me head. Well after a week me n the dude stopped talking and went ghost, so after like two more weeks me n my ex started talking again and then we got back together. Well the dude I messed with ended up dating his sister and got her pregnant, and I told my boyfriend I messed with the guy but I didn’t specify what we did, idk if it’s my guilty conscience or what but idk what to do. I don’t wanna tell my boyfriend about my private things that happened when we weren’t together but he asked me if I did anything with him and I told him no.
