Did I do the right thing?

I was friends with my ex for a long time before I blocked him on every social media platform. Yeah I was the one who broke up and I was the one who asked if we could be friends...
We ended it on a good note and became friends. He was nice as a person and the conversations we had were entertaining but I could never see him romantically, he accepted that and we just went on as friends. But he used to keep sending me reels that said that I was the best girl he had ever met or that he wouldn't date anyone else but me and I was pretty uncomfortable by it, he's just a friend and I didn't see him that way and he stopped when I told him not to do it.
I felt really guilty and selfish for being friends with him when he's giving hints that he still likes me, so one day I just decided to ask him straight up.
He said that he is waiting for me to be ready for a relationship again so that I would give him a chance, no matter what my opinion on it was. I told him many times I'm becoming friends with him with the assumption that he doesn't think he has to wait for me. So this time I just blocked him immediately, not out of guilt but out of frustration and sadness.
I don't regret that decision but I still feel so bad that I was the one who asked to be friends yet I'm the one who's blocking him at the end of everything...
