This sounds like my partner. She messages people telling them we're on a break (when we're not), that things aren't working out (just after asking me to marry her), that she doesn't want to be with me anymore (literally an hour after telling me I'm the best thing that ever happened to her).

I'm almost positive she has BPD, and this is something we're investigating, but it hurts. It hurts to think that those things may be true, but how could they be? I know my own relationship, right?

It's like walking through a minefield sometimes. Anyway, if you want to talk feel free to send me a message. And good luck <3
