I‘m a non bpd person who has contact with someone with bpd and i‘m still learning and trying to understand bpd symptoms and triggers but i‘ve figured out i triggered the bpd a lot and wasn‘t really aware of it now he‘s basically angry with me, hurt, disappointed and feels rejected which wasn’t my intention to make him feel like that he‘s seeing me all bad his text messages are short and cold and when i called him he acted cold aswell i honestly just want to reassure him and tell him that now i‘m aware of the shit I was doing but i feel like it‘s too late, i feel like he wants to cut off the contact and i‘m scared to be abandoned as well but I don‘t know how to tell him 
Is there still anything i can do or should i leave it once and for all? :(
