Have you dated someone and realised they don't like you back?

Hi there. I (26F) am going through a really difficult breakup and it just ended by us not talking anymore. I am not the confrontational type so I do not see myself reaching out to him (24M) to find out what happened. I did however ask for a phone call one time and told him that I noticed him being distant, and that he's not engaging with me as much anymore. He apologised and I thought we were good until he fell into the same pattern after a week. As I was reflecting on the relationship I'm realising so many inconsistencies which make me think he actually didn't love me. Infact, he didn't even like me. I really am thinking of just ghosting him.

So I would like to find out, has anyone here ghosted someone when you realised that they didn't love you back? Did they ever reach out when they noticed your silence? Or if you have dated someone whom you didn't like and had a messy breakup with, did you reach out to them a while after to fix things or apologise? Any regrets? Thanks.
