Am I wrong to react like this?

Someone Ex/dated in my past one day told me long after us parting ways that now he had gotten help with the one thing I had struggled to get him to realize he needed help with and left him over. He gave credit to one person I know did not lift a finger to help me out helping him whe we were still on. He told me basically that other people in his life has tried to break through to him, but it was this one moment when this person, who he had clearly put on a piedestal for reasons unknown, walzed in and told him in one sentence or two he needed help that he took it serious. The only thing I can imagine this person doing this must have been because everyone else had in vain tried and now this person felt pressured to do something. Im sorry but that is what I think.

My ex sort of shouted to the world giving this one person the award, all the credit.

I did not know at first if it was a slap in my face for having left him but it did feel like a slap in the face no matter.

I said the usual stuff sort of good for you, keep up the good work, wishing him well, at the same time trying to end the conversation and be on my way.

He would try to later on reach out to me, I could tell he wanted a second go, now that he was free from his issue, as if I would do that.

I have always felt it is important to give credit to team work.

I had felt unvalued during our relationship over this, seen our potential bright future go up in smoke.

I could not even shape a word, less a sentence to him how it made me feel and I can imagine the rest of the people still active in his life when he did this. I felt sorry for them. I felt I had made the right choice to walk out when I did.
