Guy's Behavior

Why won't he accept my apology?

(Not someone I'm dating or ever dated- just someone who I have feelings for, and he knows I have feelings for him because I told him). Anyways, I was really annoying towards a guy by deciding to come in and out of his life whenever I felt like it was good for me (being friends with him was hurtful for me since I felt like he sort of led me on). He got really annoyed one day however (because of all of the in-and-out) and told me I needed to take away from him for good, and I asked if he meant forever, and he looked at my message, and didn't respond. So, I sent my final apology a little over a month ago and basically told him I felt super horrible about everything, and that I was going to leave him alone for good (I have no clue if he ever read my message or replied, because I blocked him after I did that out of fear that he wouldn't reply). Well, I didn't stick to my words because I reached out yesterday and followed him on Instagram again, pretty much apologizing again and that I felt really embarrassed about everything. He still hasn't replied and hasn't followed me back.

I just think that if he really wanted me to stop reaching out, he'd block me. I just find that the fact that he's ignoring me like this is just flat out fucking rude, especially knowing how hurtful this is for me. I don't even think he was hurt by what I did, I think he just found it annoying. I'm so ready to stand up for myself and just tell him that if he had some respect for me, he'd at least say something; at least, he'd tell me to fuck off, or tell me that he won't forgive me, that he doesn't want me to speak to him anymore. Leaving someone hanging there is just so hurtful, especially when they know the other person is hurting. It's almost like he's getting a kick out of watching me always come back.
