How do I move on with out feeling guilty?

My ex and I broke up one month back. Why do I feel guilt in moving on. I fought hard to keep the relationship. ( I have never lied or cheated or was rude during the breakup or due the relationship) He’s told me he doesn’t want to be with me. And some other stuff I’d rather not get into. I blocked him on everything (I even feel guilty about that). I just want to move on in peace but something keeps holding me back. How do I just move on? Is this part of moving on?
