Idk what to do

So back in January me and guy were dating and I broke up with him because he was a little controlling and he was always threatening to kill himself because he was afraid to kiss me.

And recently he added me on snapchat witch I thought was kinda weird and a groupe of my friends went to the movies together and ig someone invited him or something and now he is trying to get back together with me and at the movie I sorta develop feeling again

Shiuld I go back with him
