Dear Free2BMe -
I'm sorry you are posting this on Christmas and I hear your pain and anger.
I can understand the lasting resentment, and now that you are separated, the feeling that you want to "move on".
But, it looks like you are actually still married to your WH, even though you have been separated for a year. If you really want to move on and do not want him in your life at all, then you need to get divorced. Is this something that is in the pipeline? Until and unless you are legally divorced, your WH has every reason to believe he has a chance to win you back, and if, as you say, he seems determined to try, then he will consider every other man you go out with a serious rival.
You are also giving a mixed message to the new man - you are still married, so he doesn't really know where you are coming from, and if, after a year of separation, you still have not made moves to divorce, he is right to say that you need to "tie up your loose ends" if you want to move on.
I know it must be really frustrating, to put it mildly, to feel that H is following you around and messing up any new R you may start, but its you who has to decide what you really want, so its clear to everyone. If you really don't want H back, then get divorced and get it over with. If you are not sure, and the thought of making that decision scares you, I think that means that deep down, underneath the anger, you still have feelings for H, and some hope. Now might be the right time to start marriage counselling. Would H go to marriage counselling at this point?
Feeling anger and resentment is a natural part of the grieving process, but you will eventually pass through it. You will, however get stuck in bitterness and resentment if you do not take positive steps to move forward. You cannot move forward into new relationships if you are actually still married.
I hope this helps - I haven't read your story, so maybe I am off base here.
I hope you are doing something nice for yourself this Christmas.
