The lies

Hi all,

I guess i have related questions for both sides:

Partner's of BPD: how do you handle being lied to, or be able to trust the things they say? I understand it is apart of the disorder, and I have had to forgive/understand why before, but this time just feels wrong. Lied multiple times when I asked something, only owned up to it when they were going to get found out but told me the "truth" behind it which just seems hard to believe.

Person with BPD: how to you cope with your impulse to lie? How do you own up to it or give your partner reassurance? I understand that the things you do, you (mostly) know are wrong but how have you learnt to adjust or get better with lying in particular?

I just dont know what to do.
