Yes. I went through the same thing about 6 months into Ring and piecing. I got to where I wanted to walk away myself. I gave it weeks before I acted on it, and that is what I would suggest you do. These kinds of feelings come and go. Give yourself time. "If I still feel this way 3 months from now then I will hire a lawyer and start the process."
I have a question though. When you first met your W, did you immediately trust her? Or did she have to earn your trust over time? I am not a "trust out of the gate" person. Whether it is a new friend, the SO of a friend or family, a new boss, employee, etc. I am distrustful until that person earns my trust. I don't think you trusted your W the day you met her. Over time she earned it. And that is back to where you are now. You rightfully do not trust her anymore, but can you trust here again in the future if she is consistent in her behavior over a long period of time?
Good advice. I do plan on giving it some time. Time to get back into great shape and improve myself enough to make it easier for me to find someone new. Time for MC and LR-ing to maybe work.
My concern is that my trust in her is what kept me blind to what she was up to. So the way my brain works is, now I am not sure I even WANT to learn to trust her and put myself back in that position. I have to ask myself even if her behavior was consistent for 3 years, is she just faking it because she hasn't met someone else yet. What would happen if she met someone new that peaked her interest? I have to ask if I want to risk exposing myself to go through this again. I am just not sure I do. Again, no final decisions will be made until I feel I have improved enough to meet someone new myself. I figure 3 to 6 months at least.
On the bright side these feelings are making it super easy to distance and detach.
