So fucking over it. My GF has BPD. Constant fighting, I get treated like shit. Gaslit, lied to. I can never speak in a conversationMy mental health is declining. I can’t sleep anymore because of her insecurities, arguments last until 11-2 in the morning because she can’t understand that I need to get up at 6am. Been with her for 5 years now. But last night is damn near final straw. But I’m stuck because I live with her
She’s been having allergies the past couple days so when I got home I washed the bedding, she questioned that thinking I had a girl over, I go to the weed shop and I’m gone 10 mins she thinks I’m seeing somebody. I go to the store 2 blocks away, she thinks I’m seeing somebody. 

Last night she went through my Snapchat at 3 in the morning while I was asleep. I guess my old ex from high school, who is married was on my Snapchat subscriptions? We aren’t friends, haven’t been in the years. But I don’t go on Snapchat so I don’t even know what that subscription means. So she wakes me up, knowing I have epilepsy, and that dab cause a seizure, accuses me of having a thing for her. This is getting ridiculous. 
Is this extreme?
