Mleigh My ex was very critical. I was never athletic enough for him (even though I was a good sport and went backpacking. Wilderness camping, learned to ski and snowboard, climbed Mt Whitney). I never could learn to surf and I swear that was a factor in my divorce lol! My oldest son has mild Aspergers and my ex could never accept his differences either.
Now I have a boyfriend who embraces my differences, even when he doesn't understand them, and is always supportive. It's great!!!
One thing about my ex though....and perhaps this is true in your case too...as much criticism as he threw my way, the SELF criticism he heard in his head was much worse. I always thought it must be very sad to live like that.
I'm pretty comfortable in my own skin, so I was able to withstand his criticism pretty well. I feel a bit sorry for his young new wife, I hope she's stronger than she looks and can survive when the honeymoon wears off and his negativity kicks back in.
