Guys I would like to have your opinion on this situation

Hi guys,I would like to expose you a situation I’m in and I would like to know from you if I’m the one that is “pretending” too much or I’ve done some mistakes or anything else. I’m not here to know who is “right” or “wrong”, I’m not here to judge anyone on their behalf. I’m here to expose this situation because I feel treated like a fool and I just want to understand if I’m just mistaken or not. I will try to be more clear as possibile but if I’m not I will try to expose it in a better way.

•I’ve collaborated with this Vocalist,obv paid as it should be, on more then one track,and I was and still I’m honored for that because he said that he works only on tracks he really likes so I was really exited about it.

•We worked on the tracks in a span of over 1 month and half and I’ve always tried to threat him with the right respect he deserved. I’ve paid every single work he have done as it should be since he is a great Vocalist and deserved every single dollar I’ve send him. For the first track we have worked on, I’ve made a mistake, expending and understanding from his words that the tracks would have been done in a few days,we then talked about it and we understood each others,and he understood my immense passion for the music and I was glad about it. After that he completed the track in just a Week. Then we moved on a new track, obv I’ve asked him if he was ok on working on a new track,specifying that if he wasn’t comfortable on still working he could tell me without a problem. But he listened to the new track and enjoyed it really much and wonted to work on it. Obv I’ve paid this other collaboration and this time left him much more time,putting a potential deadline after almost a month (thinking was enough since on the first track he needed something between 1/2 weeks).

•here started some of the strange things,I’ve asked him just for a quick demo after 2/3 weeks he was working on but nothin,some time without have any response. Then I had to delay the potential deadline of some weeks but in the end he made the vocals and sent to me.

•After we finished working on the tracks, knowing that his help would have resulted in us having a better reach I asked him if he could just do a Insta Story or a post here on Reddit. I’ve tried to ask it clearly as possible,telling him that there was no problem if he wouldn’t want to do it and that he wasn’t obligated to do it. He accepted telling me he would help as much as he can. I’ve asked him if he wanted me to pay him something for the “promotion” since he is way bigger then our band/project. But he refused telling me he was feeling bad to take more money from me. So just to be sure I asked him one last time if it was good for you to help us a bit and he confirmed me that he would like to help us.

•Here starts the thing that started to made me think that I was treated like a fool. Just a few weeks before the release of the track he ghosted me,if I was sending him a message he didn’t reply at all. But I was thinking it was just a coincidence,maybe he was just busy or else. Than arrived the day of the release of the tracks and I’ve send him every link for the eventual Reddit post if he wanted to do it,and tagged him on Instagram for the story so if he hadn’t the time to publish a new story he could just repost my story with a text or something. But nothing. I’ve waited a few days and send him a message telling him that if he changed his mind or anything else he could just tell me and I would understand without problem,but you know,I just want to know what he would so if he didn’t want to do the post I would try to do else my self to “promote” a bit more. But as I said I was literally ghosted,no a single response but I still waited. After waiting a few other days I’ve send him the last message since I didn’t want to be oppressive or insist too much. Just telling him to confirm me that he would not “help us” so I would organize in a different way. That message is almost 1 month old and I haven’t had a response yet.

•It’s an exaggeration feeling like a fool or being treated like a fool? I’m not trying to put the Vocalist in a bad spot or judge him because I’m no one to do that but I want to understand. Is for that reason that I have waited so long,because I don’t know what people thing,I don’t know the real struggles of people in their life etc. So maybe he had a bad time or was busy or anything else,and I’m not talking about the post or the story but only about having a response. But now after over a month and seeing him respond to almost everyone here on Reddit but still ignoring me I start to feel like a fool. I’m just exaggerating? I wasn’t suppose to expect a help from him even if he said it ?
I just would like to understand
