I've been following 2Steps situation for awhile and I can't agree that it seems like his wife has moved on.
I understand why he might feel as though she continues to try to keep him on a string 'just in case'. I can also understand how frustrating that can be.
2step, I hope when you do speak to your X you are able to manage your understandable irritation and ask her as calmly as possible "What is it that you want from me at this point? Being your long distance friend isn't working for me and I'm wondering what's in it for you.". I hope things work out for you the way you want.
