Bottling up his emotions

So yesterday me and my boyfriend had a crazy morning but that’s a whole nother story on its own. But last night we were talking about everything and he tells me his mom had a slight stroke to months ago. She’s ok now but he’s really worried about her and how much she works. He makes music and spends a lot of money on a lot of music things and stuff for other projects which has been a slight problem in our relationship. I’m all for him doing his music but he would be making big purchases every check. And 2 months ago around when it happened I could tell something was off and he ended up dumping me because he said he had to much going on. We only stayed apart for about a week but I thought it was because of me and looking back now I don’t think it was I think he didn’t know how to handle his emotions and keeping them bottled up. And we would get into little spats recently about me complaining about my mom and I wouldn’t understand why he would be upset about it. And since he finally told me he’s all do you see why I grind so hard why I work so hard on my music I need to make it out of here and I need my mom to stop working. Like yes now I get it but I’m honestly mad he took so long to tell me. I’m here for him 100% and I’m such and open book to him and it hurts that he doesn’t feel that way towards me. It kind of makes me feel like I don’t want to be in this relationship anymore. Am I wrong for that ?
