An important – but hard – lesson to learn in life is that you won’t get closure from everyone. But you can take steps to move forward on your own. Based on what you wrote, and the immaturity I see on his part, I doubt you will get the closure you need from him. He sounds immature and manipulative, treating women as objects to satisfy his needs rather than actual human beings. These are not desirable traits in a partner so from the outside, it would appear that you are better off for being rid of it.

Having said that, I know it’s not as easy as “letting go and moving on”. You shared a history with this person and I understand the pain of feeling used and discarded by them. I’m really sorry you experienced that. Time will need to run its course. Right now, I think the best thing you can do is block his account (and his ex/current?). Don’t invite that into your life.
