Help Plz

I used to talk to this guy about 1yr and half ago it was long distance we both seem to really like each other his personality was amazing and he just seemed so perfect but then we just stop talking like he stopped texting me and answering my calls but I eventually found out after we stopped talking I saw on his twitter that he was married I knew he had a son but he always told me him and her wasn’t together and basically he was raising their son and lately all I’ve been thinking about is him I’m kinda mad that he didn’t tell me about that but I’m also just like I miss him so much I really want to hit him up but I don’t know what I should do PLZ Help!!!
