This Weekend Was Tough.

so on Sunday morning, I wake up to my fiancé blowing up my phone because I hung out with some friends the night before. there was a little drinking involved but not enough to where I was drunk. he wanted to cuss me out and call me every name in the book. I asked my friends what I should do. he's been turning really controlling the past year. we have been together 4 years. everyone's telling me to leave him but my heart says otherwise. ladies, what should I do?
