Why do i feel this way 😢

I sometimes feel like I do my best to try to please my bf and be there for him when things go down hill but when it comes to me its like he's not even there for me. He's going thru some things right now and I know family comes first but all I want him to say is that he's here for me like I'm always there for him. I keep crying because I can't help it idk maybe I'm over thinking things but I have feelings too and a relationship should be 50/50 not 80/20
