My worst fear is that my fiance will leave me or cheat on me after our son is born.

I amworried because in the past we have had hookups (3somes) because I am attracted to girls too and sometines want something different so we share, I figured a win win, he always treats me like #1 so I know he loves me but he made a comment asking when we will have anothet 3some.... "I'll be good for another year" like he has to have sex with someone else to stay with me? I may be over thinking this but I'm just scared because I see all of these stories where guys cheat after so many years and the girls never thought their man would do something like that.

I'm also worried about postpartum when I cant havr sex and if my vagina will feel the same and satisfy him? If he Will still be attracted to me... There is just so much unnecessary negative thoughts going on in my head and yes I havr askrd him all yhe wuestiins and he assures he lives me anf hes so excited to be a daddy so all of this insecurity is all me but I figure I better be cautious.... Idk
