WH, Thank you for your amazing support. I know how hard it is to get on here and respond to everyone else when you are struggling yourself, so i really appreciate you being there for me!
My experience is like yours - that you cannot shield kids from this type of insanity... I'll admit that I could be doing a better job, but, it's HARD, as you know. My XH says and does strange unpredictable, cruel things to our kids (my POV, I know) and I feel like I'm constantly just picking up the broken pieces that he leaves.
But anyway.. the responses I've received here have worked to remind me that i can't drop the ball with respect to my kids. This "News' from XH has really shattered them - and I need to keep working hard to ensure that they are as OK as can be. Sometimes its easy to focus too much on yourself or feel like it's all some sort of crazy dream that cannot possibly be real.
