His mental health hasn't been good lately and i've been trying to support him however i can. He told me he constantly has a "push and pull" mentality about me, sometimes he loves me and other times he despises me with "everything in his being" and i tried not to get offended as i'm used to him often seeming angry at me and telling me to go away etc. I'm quite patient and I don't blame him, i just try to help him. I always let him know that i love him and i'm there for him. Basically i'm looking for advice for making a relationship with someone with bpd work.
