I dont know mannn..

So me and my bf have always argued about stuff we've been together for 3 years and no matter what I have the feeling of not wanting to let him go we've been through a lot together and he means alot to me but lately I've felt like he doesn't appreciate the things I do for him , sometimes I feel as if he's ungrateful and like maybe I deserve more and long story short i sometime wonder what it'd be if we broke up , would I be happier or is this just another rough Patch and like I'd never change the person he is but I wish he'd change his attitude towards me at the moment , I just don't know what to feel.
