I think I read that it stops progress and the MLCer can be stuck there forever at this point. Wanted to check to see if I was reading this correctly that marriage seems to rule out any chance of reconnection as know I would be the ow!
No that is not true.
It makes more destruction and more difficulty in reconnection.
Read Don't Give Up, his wife has divorced him married an OM and he is still standing.
That does not mean waiting though.
You must get on living your life.
We can not tell you what your boundaries are, if he has crossed them to the point that you would not remarry, then tht is your choice.
However what I think you may find is that if you were to remarry anyone that had already been married then you would be an OW.
Really that is just FOOD for thought.
I would just worry about you right now.
You are no where near ready to be in any relationship right now, IMHO.
Him destroying everything is just part of the script.
Let him go, for you are right that now you wouldn't want him the way he is.
Hope this helps.
