Advice, please? :(

I have been with my current boyfriend 6 months as of today. I've known him for almost a year and we were really good friends before we got together. My last relationship was awful, so I have trust issues and a lot of other things. I always ask questions and I ask them a few times. I just do (no rude comments please). Anyway, for a while I felt like something was off. I asked him a nd he said everything was fine. I asked a few times over the next couple days, he said everything was fine. I was talking to him Tuesday night and I asked if we were okay. He said maybe. We talked and talked, he called me and we worked it out. We agreed to listen to one another when some things wrong and to not argue anymore. So far we haven't argued, we have only talked. Which is really nice. Last night we were talking and he said he felt like something was off, but he didn't know what it was. I asked if i had done something, and he said no it had nothing to do with our relationship. Then he said he needed to figure himself out, so we talked about taking a break and space (we both work, and he had to do a double yesterday and asked to reschedule our plans, that's how this all came about) he said he didn't feel like a break was necessary that he just missed his free time with his other friends. Which, I get that but he doenst always have to tell me yes, you know? And he also said us taking a break meant not talking or hanging out for a few days because he wanted "seff time" (his name is seth, but i call him seff sometimes😂) Hes a gamer, he just bought almost a $300 desk and spent almost $1000 on a computer that HE built. Im extremely proud of him, he works for what he has and he supports himself. He plays games alot, which is totally okay, but when he does, he doesnr always tell me like "hey babe im gonna play some games" usually he will just not reply for a while, which makes me worried. Anyway, he works 5-6 days a week, some morning and some afternoon. Yesterday and today he pulled and will be pulling another double, which totally sucks. Some days he will ask if we can reschedule so he can get some sleep, and he'll sleep all afternoon. I don't have a problem with that obviously. He tells me he loves me and he wants us to work but he's been acting so distant. He said us arguing us what making him feel this way because we do it so often and over the stupidest things not even worth arguing about. I love him, and I know he loves me. He treats me wonderful and spoils tje crap out of me. I just got my job and now I will be able to do things for him, which I'm really excited for. His parents invited me on their trip to Cedar point this summer. When they go out and I'm at his house, they'll ask if I want anything. It is literally perfect other than when we argue. Any advice? Please keep your rude comments to yourself, I'm not in the best shape right now..

Overall, we have a great relationship, and friendship. He told me that I was the best thing to ever happen to him, and that I was the best girlfriend he's had. I'm annoying, and I can be mean at times but that's my baby. We went through something much worse than this about 2 months ago, and we got over it, no problem. I'm doing everything I can to be good for him. I got back in school, I'm able to drive and I have a job. He makes me want to do better, to be better.
