Why won't he block me?

Been talking to this guy for 5 years now, I'm really in love with him he was there for me during the most hardest times of my life, he told me loved me multiple times I figured we were ok, but I found out he's been talking to a number of females online and this is killing me inside. I'll hit him up and he'll ignore me and message me whenever he wants but he's been distant. I'm very depressed at this point and I can't stop contacting him because I'm emotionally attached. I asked him yesterday to block me so I can heal but he said he won't do it. I feel like I'm losing my mind, I'm very hurt. How can I move on from this without him giving me access to him? I know some will say just move on or just block him woman up but I can honestly admit I can't I love him too much. How can I move on from this? Is it wrong that he won't block me? Thanks for hearing me out.
