Okay that's good to hear. I've read that no situation is impossible but with mine he said that he wants to be single so he can figure out where he wants to be in life and is going to be single for a long time and he has his mind set on that. Then a couple weeks ago before he blocked me I told him that I agreed with the breakup but I still wanted to talk for closure but now I realize that I don't want that. Will positive thinking and using the LOA  help? I visualize him saying that he wants to talk and that he regrets saying all the stuff he said and I visualize the good times we had together. I don't know if my chances are ruined for good.

Okay. You're right he could change his mind. He said that he likes being single better and that some people like being single and he's one of them. I initiated the breakup first and then after not talking for 2 days I decided that I missed him and I asked him if we could talk and that I wanted to work through our problems and that's when he said that he likes being single. I've been saying positive affirmations to myself. Does it matter how bad a situation is?

First of all stop repeating the story of blocking. Not even to urself. Forget that he has blocked u. Move on with ur life as nothing has changed. But keep up with the visualisation. Do this for a month. And then see the results
