Relationship advice

I just feel so confused and alone . My bf and i are literally just laying in bed rn not even speaking . We have so much love for each other but when our problems hit they hit hard . I cry a lot . I know the problem is me that i complain about everything. I know i have a problem with Complaining, i hate being such a negative person and i feel like I’m just letting him down. He’s a good person and a good bf but i hate when he makes me cry and lately I’ve been so sensitive so i cry so much more probably because my BC. Do i let him go and find better even though it would hurt me so much
