I recently broke up with my boyfriend, what should I do?

We had an on-and-off relationship because of his lack of communication and empathy. He was very unstable. Like, one time I didn't text him all day and he told me not to do such things because it made him worried, but then he started doing the same thing, didn't call, didn't text, left me wondering what he was up to all day and this happened multiple times. He told me that he loved me but his extreme unstable behaviors were tiring me out. He said he didn't want to break up again. But we were barely talking and he wasn't trying to fix things. I put in the effort most of the time. Then we broke up, this time he wanted to, even though he had told me that he didn't want to break up ever again. He would call me a few days after every break-up but this time I got no calls from him. I sent him one last message, wishing him a good happy life, saying I'll remember the good memories and stuff. He thanked and said "I love you. I'm so glad to have had you. Always be happy. Goodbye, my darling."

I don't understand why he was so unwilling to communicate with me. All I asked for was small talks during a day. He didn't like it when I did the same thing yet he kept on cutting off our communication.

Will he ever regret, call me or at least think about me? Should I just let go? I'm still in his contacts and we follow each other on Instagram but he isn't active on there.

Even when I'm trying to end our relationship on good terms just to be able to forgive, forget and move on, he calls me "darling" and says that he loves me but he doesn't even try to fix anything.

I hate that I still think about him and I wonder, did he just forget about me?
