I have given up unfortunately. I guess I just don’t have the patience for this, and she has done so much that I don’t see her ever coming back to the marriage.
You had a whole list of things in your first post that you needed to work on. You're too young to be moving on to marriage #3! Look at your thread title- "Emotionally Unavailable". Do you really want to carry all this baggage into a new R without doing some work first?

Maybe way down the road she will have regret, but I can’t wait around.
What would she regret?
"Looking back we certainly should have spent more time learning how to communicate with each other."
You are a poor communicator.
"After we got married we did start to grow apart and I really see it was me just not allowing myself to be fully open with her, something she desperately wanted."
You've built walls around yourself and don't let her in.
"She did try to communicate this to me, but I always took it the wrong way, like she was attacking me, and it just further solidified my confidence issues with her, to the point where I just started to shutdown."
You are emotionally unavailable.
"but goes back to the fact that she can't get the loving feeling back for me again because I made her feel so unwanted and hurt."
You emotionally abused her.
"I drove her away"
Speaks for itself.
So how have you become a man she would regret not being married to? And how have you become a new and improved man prepared for a new relationship, and not just someone ready to repeat their old mistakes?

I will say I happened to meet someone and get a date for valentines weekend, I’m sure that is helping with my attitude. It just sort of happened, so I’m going with it!
Do you think that's a good idea for you or the other woman? Have you discussed this date with your IC? If not then you should.
