On leaving my ex-husband:
I had been miserable for some time and trying to find a way to resolve it. He was not open to counselling or making any other changes. I stayed mostly because I knew he'd crumble without me. Anyway, one morning I was feeling particularly miserable and he told me that me being miserable was too hard on him. I had an epiphany and decided then and there to leave. I packed a couple of bags and was gone within the hour.
I spend the first couple of weeks in a state of shock....made even worse because his refusal to socialise had left me without friends. Then I started to feel better and started to reconnect with old friends, go out and have fun. Two months later, I met the man who I am still in love with 21 years later.
I never regret ending it. Nor do I ever look back with sadness. Life is great
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
