No bonding no nothing it’s shit

My boyfriend have been together for five years we are still young 19 and 20. For months now my boyfriend and I don’t see each other because he’s busy boxing and is there for hours and goes everyday. Now it’s just has gotten to the point where we only see each other once a week. I’ve told him how I felt about it many many times and that I just wanted him to give me a little more time just so we can bond but he gets mad and says “so you just want me to stop boxing completely and always have time for you?! When that’s not what I want. I want him to keep boxing because he loves it but he goes everyday. I just want him to dedicate a little more time for us and atleast not go box one day. I think bonding with your boyfriend/ girlfriend is very important and that’s how we get to grow and be closer to one another. We don’t bond anymore. We don’t do shit. It hurts me because I miss him and if he would care about our relationship he would atleast try to make more time for me or atleast make it a day where he wouldn’t work out/ box and dedicate it to see me. This has been going on for months and he still says he loves me but he’s so fixated on boxing so it’s like 😐. Makes me want to break up with him because it all makes me think that he doesn’t want to be with me. I support him, I’ve been supporting him going to box everyday but it’s affecting our relationship. He hasn’t done anything to fix the situation and I think it’s because he knows that I won’t leave him but I really want him to fix this. This is literally what we argue about all the time I’m tired 😢I also tell him if he feels like I’m just a bother in his life since he’s so busy he says no that I’m not that he does want to be with me but he doesn’t show it. For worse since we don’t see each other, he be having crazy mood swings and gets mad at me for stupid shit over text which is so stupid. Any advice
