How to handle my relationship?

ok so this may be kinda long so I am sorry about it I just want to explain it all so I can get the best help!

ok so me and my boyfriend have been together for a month. we where together before but we broke up for about a month stop talkin to each other and everything, we decided to try it again. so I’ve been haven these feelings like he doesn’t really care about how I feel and all that matters is his feelings and whats going on in his life. I mean I had a scare from a doc app. that I might have cancer and when I told him he was like its nothin to worrie about yall be fine, you over reacting. and yes it does turn out that I’m fine I just have to keep a check up on it but later on he did say sorry about not being there but its too late its done and over. then his family got into this big fight and I was there for him the whole intire time. but when my family had a prob he got into a fight wit me about it and wouldn’t help me out and still hasn’t called me since and its been like 7 hours.. I just don’t know what to do anymore I feel like I’m losen it when I’m wit him and I feel like I’m losen it when I’m not wit him.. I love him but I don’t know if I can keep going on like this.. relationships are ment to be a team work not me support him and him not support me.!! What should I do I’m so lost.. And its like he’s trying but he aint…
