i try so hard to be there for her and make her feel better when she's feeling down, make her life easier, everything, but i think i'm pretty horrible at it. everything i do seems to annoy her so much and she gets extremely caustic so that's very painful to receive but i also understand and idk what i can do. 

my bpd makes it worse because every time it happens i question everything about the relationship, whether she'll eventually get so annoyed she'll stop having feelings for me, or whether she's just staying with me bc of circumstances, or that she's doubting the longevity of the relationship, etc. just absolutely crushes my mood and i feel completely useless. every day it feels like she loves me less although i know that's likely to be untrue. 

i don't know what i wanted out of this post, i guess it was just a rant and maybe seeking some advice.
