BOYS😫😫😫

I need your advice girls!!! So I've been on and off talking to this guy for over a year now, nothing official and nothing exclusive as he moved away. Recently he deleted me off snapchat as he told me I was "too dramatic", and we didn't speak for a couple of weeksI don't sleep around, and haven't had sex in months (bearing in mind this guy lives far away from me), but this morning I had sex with someone, no strings attached. After I had sex with the other boy, this guy started messaging saying he was sorry. As to not keep secrets I told him about the sex, then he claimed he could no longer talk to me as I "broke his trust". Do you think what I did was wrong???? Or is he overreacting???
