Ex problems.

Hi I need some help so I was in a relationship for 4 years and towards the end of our relationship things started getting a little hard he became really demanding and strict. I couldn’t do anything couldn’t go anywhere, I had to wear certain things and all of that bad stuff. I stopped being happy and insecure and really stopped doing a lot of things I loved lost a lot of friends over this. So about a month ago I broke up with him because I just couldn’t anymore I wasn’t happy my family noticed it and so did my friends that were still sticking around me, long story short he texts me or calls me crying and he just saying he misses me and has been trying to be very manipulative and has literally told me he was gonna commit suicide if I didn’t get back and I contacted his family and everything and I’m just scared just need opinions on what to do cause I’m scared and confused and it’s ok if some of you guys think I’m dumb cause I feel dumb myself.
