Go slow. Be her friend right now. Are there 180s you are doing to show her that you are working on things? By working on you, then you can show her you are trying. We can only work on us and hope our spouses notice and will be attracted to us again.
So work on you--GAL, detach, act as if you are happy when she is around.
Maybe you can slowly add things in, like asking her to stay and watch a movie. Just remember to take it slow and don't push it or get too excited if she says yes. Let her set the pace. If she says no, then say okay like it doesn't bother you. Don't let her see that it hurts even though it does.
Have a good evening! Will check back later. Sherry
