I have to agree. I 'changed myself' and didn't like who I had become - someone who was constantly feeling like my marriage was always on the edge of a cliff. If I 'messed up' she'd be gone again.
I did mess up eventually, I mean how long can you carry such an emotional burden on yourself.
So now I 'get it', that I need to believe that I'm worth being with just as I am. Flaws and everything. And that a good partner will help me when the flaws show up.
Right now I only have myself, so I have to help myself with those flaws.
As far as the divorce, I am going to see how quickly I can get it done. With luck W will be single again by her birthday in July.
