I hear what you are saying. My ex has a lot going for him too.... or so it seems... the truth is, we don't know what is going on between our ex's and their new wives. Likely, the same things we had to deal with. How much fun can it be to be married to a man who would use abuse to solve his marital conflicts. Believe me, you are better off, really than he is. You are out.
Moving on with another man... well, I say cut yourself a break. You have a lot of healing to do when you are betrayed by someone you loved and trusted. And frankly, there are not that many single men out there who are healthy emotionally. The majority of the healthy guys are with their wives and living their lives.
I don't say this to make us feel bad. I say it so you will stop blaming yourself. Its not your fault that you haven't moved on. I say wait, wait, wait until you feel healed from the wounds of an abusive marriage and until you have found a healthy partner who will truly have your back in life.
And in the meantime, please live this wonderful life that you have with joy. Go out to dinner with friends. Reach out to people, again and again. Volunteer. Go to church. Stay involved in the world. And be grateful that you are out of a terrible marriage.
You are special and God wants only good for you. It will come in all types of forms.
Take care and please remember that you are not alone. We all feel this!
