25years MLC nd City Girl will respond to you, I am sure.
You made some telling statements here:
"I am not sure what I enjoy.I have never really enjoyed anything without her"- it sounds like you do not even know who Kevin is and that W was a distraction that allowed you not to focus on your own shortcomings. Instead of developing yourself, you focused all your energies on her.
"I wanted a W so badly and when I got one I screwed it up" - is it possible that you wanted a W, she came along and hey presto? Was she really even the one for you or was she there when you wanted a W? What do you love about her - you have never said this. Was she your first real relationship?
"There has to be some way to act fast and get her interested in me again" - see all of MLCs and City Girl's previous posts to you. In a word, no.
Unless you work on Kevin in a fundamental way,these problems would still resurface even if she came back. You want to apply a band-aid to an incision. It will not work....
