I'm so sorry you've been treated this badly, KD1980!
I COMPLETELY AGREE with what all the other wise, wonderful posters have already wisely said better than I ever could! He DID act very childish and I'm REALLY HAPPY that you're realizing that and that you're not blaming yourself because of it because it WAS NOT YOUR FAULT, KD1980, of course!
Keep working with your therapist! Right now you're dealing with your past experiences and it will be a little painful at first, but I'm SURE that you will feel better and better after getting through ALL OF THIS, KD1980! I PROMISE YOU THAT! PLEASE REMEMBER ALL OF THAT BECAUSE IT IS TRUE!!!!! Just keep fighting, keep working on yourself and keep trying your best, ok?
That's ALL we humans can do after all and it's ALWAYS more than enough!
I'm wishing you PLENTY of peace and quiet, KD1980, especially within yourself! Sending many hugs to you, KD1980!!!!!
