Wow! I've just read this thread and it has blown my mind.
I was like this with H. Couldn't put my finger on why at the time but in hindsight it was partly his critical nature, perfectionist tendencies and me putting pressure on myself to be 'on call and available' for him created a stubborn inertia.
I began to relish time alone when he and DS had gone to bed. I was able to do what I wanted, in my own way, in peace, guilt free. But H got frustrated that I wasn't going to bed at the same time as him.
Fast forward and he told me he wanted to end our marriage in the spring. I was heartbroken, and spent time flailing and trying desperately to understand how things went so wrong without me realising.
After he left I didn't seem to know what the hell to do with myself. In hindsight I just didn't know how to be that main character in my life. My role was as a supporting character but with increasingly independent teens and H gone there was no main character to support.
8 months later and although I can't quite say I'm glad that he left I am getting there. I am learning to do what I want, when I want and how I want and it is new, and exciting and empowering. I have remembered what lights me up and I'm starting to do it- wild swimming, late night catch ups with friends, hiking, yoga, eating, crafting (badly but who cares), listening to loud music.
My wonderful friends have carried me through and several friendships have become deeper and stronger in a way that would have been hard for me when I was a wife. I feel incredibly lucky to have such amazing friends who love me just as I am, despite many imperfections. I value them too much to ever prioritise a relationship over strong friendships with people who have shown me that they will show up for me unconditionally.
I totally accept this is not what I wanted but in my case this enforced singledom looks like it might give me a chance to be the main character in my life- and given that I'll just get this one wild and precious life I think it might have been just what I needed.
NB I'm not suggesting for a moment that anyone else would be better off single, or that one needs to be single to be themselves.
