The other day i made about this same situation and it’s still tearing me down. my ex and i broke up the other day, and while i know my bpd (just constant mood switches/seems like i’m mean/seems like i’m just in a shit mood/bad attitude) is a part of me but i cannot stop thinking that i ruined our relationship and i feel so awful for hurting another human being. 

The night of our biggest fight i’ll give examples of some of the things he had told me; “i just want to start by saying you need to treat people the way you want to be treated.”
“you gotta get it together. cause i just can’t do it anymore.” also mentioning that i have really poor trust even though he gives me all his love and compassion and time and energy.. im fucking hating myself everyday because of making him feel these things. i don’t want to blame the bpd, and i’ve recognized these behaviors with a diagnosis about a month or two ago. i wasn’t always kind to him and he was a very loving partner and a really sweet guy so it destroys me that i’ve hurt him so much. please, if anyone has literally ANY input or advice please let me know :(
