After 7 months I am still saddened over it ending... Advice?

I am a senior in college (22) and was 21 seeing a 37 financial advisor divorcee (in debt) with an 9 year old son... We had known each other for a bit over a year (mutual friends) , and had been "on and off" for about 8 months, but 3 months consistently, I cut if off both times ( 1st time he was inconsistent 2nd time he didn't commit)...

After a small argument (via text) about how I had a stalker and ranted to him, he told me "no time to respond to paragraphs with my son" after I said it's lowkey kinda rude when he doesn't respond to everything I said (gave me the silent treatment for 2 days until I apologized)... So I stated I'm not going to wait for me to give me what I want/ need and said we need time “to cool off” since it was my last week on my 5 week business trip after that week ( be began to apologize w/ all his hard claiming that he was just overwhelmed)

... After, we made small convo and let him know I made it back to our state. After, the awkward convo, about 2 weeks later I reached out again (another short convo), and just ended it with " Well, I hope you have a great rest of your day"... Then the next day I see he posted a picture online w/ two beautiful women on his left and right, so unfollowed him on all social media (like blocked and unblocked, so he's not following me).

I'll headed to grad school right after undergrad, have great friends/support system (something I didn't have when I was entertaining him), take care of my looks/super health conscious, do therapy, professional model, travel... WHY am I SO depressed over this still... It sucks caring so much/hard about people sometimes, its hard to genuinely let go...

I'm also upset how he would come back a SECOND time, introduce me to all these people and say he "needs more time to get to know me" what.
