I need help I’m in high school?!!!

All I wanna do is cry and scream. My boyfriend and I have been having problems and I think it’s just me but I’ve notice that my boyfriend has been very quiet or “tired” and all I do is worry. We broke up for like an hour on Sunday because he wanted space and he has a lot on his plate. But we ended up getting back together because of him. I was talking about how much he means to me and his self worth and he said he wanted to get back together and I asked him why and he’s like ur caring and I asking him on Monday and asked again and then he said because ur caring and I love you and it felt good but at the same time it didn’t seem very true. I’ve been asking him if everything is ok and he keeps saying that everything is ok and nothing is wrong and he’s just tired but I feel it in my gut or in the tone of his voice and fac that he really isn’t ok. I’m trying not to over react and I’ve been giving the space that he wants but it just seems off and idk what to do and people are saying you should end it. It isn’t worth ur pain but I want to be there for him and I wanna work things through. Idk what to do because idk
