(((((((POSSUM)))))))
He hurt you I think because he was hurt. I've said before now, we expect people to understand how we feel and they expect us to understand what they put up with; it is very hard on everyone.
But he shouldn't have said that to you at all. I fully understand your problems with past abuse and how that ruins trust; I've been there myself and it takes a lot to get over. Just know that you are fully supported here
As for understanding the man, you need to decide first if you want to understand him or work on yourself,
Loving thoughts,
