Will he regret and comeback?

Me and my ex bf been dating for 3 years. During the third years he started cheating on me. When I found out he apologise and promised to not repeat it again. But soon a week after he still doing it. For months. I just pretend that I didnt know. But then I was so upset and confront him again and this time it stopped. However the damaged that he caused has led me into toxic behavior such stalking him online. I keep an eye for his every movement online. And he knew it. Until I keep stalking him again and again and he is tired of everything, he decided to end us. He left. He said cannot do it anymore. He said he lost his feeling and feel no connection. And he said that he wont comeback but he want to keep me as his friend. I refused because I can't be friends with him. 2 days after breakup he started following some random girls and liking their pictures. The first 2 weeks after break up I convinced and begged him few times. But it only make him get angrier. So the third week i stopped contacting him till now. I am in No Contact day 10. I blocked him on whatsapp and he messaged me on *** and said "just block me on *** also because you already block me on whatsapp. Just remove me in your life cause i dw to be part of it anymore". I just ignore his message. But till now he didnt remove or block me on any social media, except linkedin. Idk why tho. I just really hope he will regret everything and wish to comeback. Well doesnt mean im gonna accept him back. Just to teach him a lesson. I was toxic too here but if not because he cheated, I won't be. And I was just trying to defend myself. I loved and cared about him with all of my heart, mind, and energy. I'm also loyal as ***. I respect and value him. But this is all what I got. At the end I don't lose him, he lose me.
