Getting upset often

hi everyone

so my boyfriend and i tend to argument a lot and tbh it’s mostly me getting upset with him

i fear he’ll get tired of me or the relationship

man’s i don’t wnat that

but sometimes i feel he doesn’t get me

and what also upsets me is i feel i’m teaching him a lot how to behave and tbh it’s tiring

i believe i fell for him cause of some certain traits and now i’m wondering if those traits were the real him or he was just trying to get me

i love him

but at this point i don’t know what to do

i want us to get along more than we argue

Any advice please will be appreciated
