I'm going to tell you what worked for me,
and what will work for you...
DATING aka SOCIAL INTERACTION with members of the opposite sex.
Nothing says "movin' on" like dating and being with someone new.

I know, you're going to say,
"but I can't do that, I'm married, I vowed to be true to my spouse, I can't resort to doing that, I'll be no better than my spouse, etc. etc." and a thousand other equivalent excuses.

Start going to the gym, start tanning, get a new hairstyle, get some new clothes and shoes, start going with your girlfriends more, if they don't go out, find some new girlfriends that do, drinks at lounges, make yourself look good and all dolled up. Date other men, it doesn't have to be serious, and I'm not asking you to hump the first pair of trousers that you go out on a date with but you need to do it. You need to know that you CAN do it. You need to know you have options, when you know you have options, your confidence will increase and it will be at a place it hasn't been in a very long time, you'll see that it's your husband's loss and you'll move in the opposite direction, instead of pursuing him you'll let go and move on and when he notices that his wife is no longer waiting for him and that she is doing the same thing as he is doing, it will give him a dose of reality. Heck if you haven't already file for separation or divorce. Nothing inspires people to action more than fear of loss & crisis. And if after all of this you get no change out of him, guess what, you have your answer as far your reality is concerned.

Those are my ideas, you are free to do whatever you would like with them.
