I’ve been diagnosed with BPD for a few years now but I’ve dealt with symptoms since about 2014. this whole time i’ve thought i was pretty good at maintaining friendships (not so much romantic relationships) and i’ve been friends with my ride or die for 12 ish years. him and i have had our ups and downs of course but we always respected eachother and tried our hardest not to be d*ck-heads cause eachother was all we had. i recently moved into an apartment 25 mins away and we used to live more like 2 mins away from eachother. i’m lost cause our friendship is getting worse and worse and i can’t tell if i’m doing something wrong or if it’s both of us. he flakes on me, doesn’t reply to my messages, he’s kinda ruined my perception of friendships therefore i have no one but him. in the past he’s had some lying problems which have resulted in me blowing up/ splitting. so we’ve both done wrong. he’s supposed to be coming over today and idk how to approach the conversation or even know how to put what i wanna say into words. i need advice.
