Im going through a lot with my bipolar ex gf.. We were supposed to get married in a month but, whatever.

My friend told me that, he has experience of putting people through BP like she is to me. My friend sad that, BP's live with a lot of regret and wish they could change things but can't... They also feel if someone leaves them then it's typical for BP's to just let them go even if it hurts bc they dont want them to get hurt and they know its their fault for what they are doing and as much as it hurts them that the person left, they live with it because they know it's best for the other person. Is it really like that???
