Alex,
I can understand your questioning how to live w/ a lot of 180's and at the same time also stay true to yourself. Especially interesting question I think when you have a half century or so of self to consider. I have also pondered this in terms of GAL b/c much of my new life is actually the life that my H and I lived together. I was not dissatisfied w/ my family or my friends so felt no need to run away from them like he did. So the real 180 for me has been to see this life as meaningful and to live in it happily. That was not so easy before he left, since he had been depressed and negative about it all for quite awhile. I am lucky that my friends and family have rallied around and continue to be good to me and for me.

Just recently someone posted about advice she had received at the beginning of her having been freed up from a long term M, to "never turn down an invitation." I am definitely in agreement with that. And then there is the obvious track of trying some new things.

I don't think of myself as a different person though. My H left and told me he wanted to "reformat his personality!!" Not my aim for myself - I am in a crisis not of my choice or making, but not a MLC. Nonetheless, changes happen. With this kind of shock, then introspection and recovery - you can't help it.
