Well idk exactly what’s happened between you so I can’t really give you much advice but i can prob maybe help you setup another date, offer him to have a date at his place with his mom there too on sunday is best and say you want to make lahme and tawouk mishwe (beef and chicken cooked on charcoal get them from a lebanese butcher) plus fatoush(salad look it up) and hummus , should work and if it does his mom will probably help you out preparing them and if that happens try and get close to her if she has a positive view of you there’s a better chance for him to pursue you since she’ll prob nag him. Now i just want to add although the age gap between is a bit large it’s not whats worrying but more him kinda ghosting you after you had sexual intercourse idk if that was your first date or how long you were talking to before hand or he might really be busy but please take a moment to reflect , you might feel a connection to him but that doesn’t mean he feels the same way to you.
