He blocked me and changed his number what do I do?

Anonymous
My ex changed his number and blocked me on social media because we fought so much. It was constantly over other girls. Usually we would fight and get back together or he would block me for a little bit and then unblock me. He changed his phone number now after a big fight I have no way of contacting him and I never see him. This hurts so bad and it just makes me want him more. The last time we spoke you told me how he hates me and he’s done with me and he threatened to call the cops on me. We have a very volatile relationship and I know some of you were going to say then why do you want this but it’s complicated. I just need advice and a perspective that can help me please thank you
