22F fallen in love with a married man 33 M

Okay so i got into a affair with a married man last year in oct and broke up with him in December and now i think i got so attached that I feel i cant move on cause he was caring mature and things. We got physical after 2 3 dates and i liked him but i think i might have fallen in love with him cause he lives in my society and everytime i see him i just miss those days cause he was my first kiss and everything and now everytime we see each other we just smile i wonder if he misses me like i do cause there’s no way i can move on even thou im trying i started talking to a guy but i just don’t feel that connection that used to be with him.

I feel so guilty of being in this affair after all but at the same time I needed this kind of love i just dont know what to do
