Recently my boyfriend got his diagnosis. He was sad about it because he knew how hard BPD is, but he was also relieved that he finally knew why he felt as intensely as he did.

He was splitting me two days ago, which ended up in a conversation where he told me how he felt something like hate towards me and he wanted to be away from me. I’m not gonna lie, that hurt my feelings a lot. I cried for super long and couldn’t grasp how he could hate me.

The next day he was again the most loving boyfriend. He was apologizing profusely, we were feeling so good and are still feeling that way. The problem is that now my sister has decided that he deserves absolutely no more chances and she is annoyed by me because I am giving him a second chance. I explained to her how borderline is and honestly told her that I am a grown woman and that my relationships are none of her business, but she is not hearing any of it. She is constantly repeating „Borderline or not, he is abusive“. 

I guess what Id like is some advice on how to handle the situation.
