My partner and I are both BPD and love each other's very very much, as you all know how strongly we can love and I find it quite funny (and somehow cute as well) that the only way to express how much we love each other is to say things like: I love you so much I could kill you.
Obviously we don't mean it literally. We have so much respect for each other, and it's hard to but in words how we mean it but I think many people here can relate to that.
