Advice please.

Jerr • 21 | Engaged | SOON TO BE MOMMY ❤️
My boyfriend and I have been together for six months. I love him more than words can explain and I want you guys to really understand that, but we constantly fight over nothing and I don't know why. We just fucking argue a lot. Last night he told me he loves me more than he loves himself and I got to thinking, is that healthy? Shouldn't he put himself first? Or am I just crazy. He says he loves me more than anyone in the world. I'm confused because I feel like his family should be the ones he loves more. Advice please.
