I recently reconnected with my ex after 3 years . It went Great in the beginning but I moved too quick and had sex too soon before I had the opportunity to make him show me he changed . So now I’m noticing a pattern . He only hangs out during the week usually Tuesday and Friday . He never asks me to hang out on a Saturday or Sunday . Obviously he never did his before but I should I suspect he is seeing someone else ? How do I confront him on this without sounding stupid or desperate ?
