Why do guys block and unblock their exs?

Anonymous
So I was dating this guy for 5 months. We were friends for a a few months before we dated. It wasn’t SUPER serious since I’m leaving for university this fall. But this situation just confuses me.

So I’m 19. The guy I was dating is 24. He has a baby with his ex (that I didn’t know about). But we got in this argument and he let it spill that he has a daughter that he never met, never took responsibility for and has been avoiding sending child support. Then goes off to say that he constantly blocks and unblocks his baby momma and will sometimes creep on her Snapchat stories where it’s just selfies of her.

I was curious. So I looked her up. And she’s extremely successful. She works in the medical field. She looks like she has a great life. While this guy works at a hardware store. Don’t get me wrong, the pay is good but it’s not something that’s good for forever. It’s something that’s good while you’re in college and he’s not in college (another thing he lied about. He told me he was going to college)

I broke up with him when all of this came out. I’m just curious. Why do guys block and unblock their exs? (I also had a diff ex who did this but he did it to me) like he’s keeping tabs on her but never made contact. Why?
