I have followed your sitch for awhile now. You seem to be a sincerely charismatic, intelligent, and happy person. Very artistic and very REAL person. Kudos to you. I like your approach and based on what Ive seen, your Wife does truly love you...friends/lover/husband/many ways.....but her actions, and yours, leads me to say......Try something different.
You can love her, but she knows you are there. WHAT IF....
You move on...I mean truly move on. "Sweetheart, I love you and I always will...but if you are not here WITH me, I can't continue talking with you...I need to move on"
It shows you care, it shows you love yourself, and it shows her enough that you validate her feelings AND love her enough to set her free. Instead of TRYING, GIVE...and walk away. Hard, but based on what Ive seen, very doable. Sometimes opposite works.
Your choice, but I hope you think about it. Validate her and make her curious as to why....might JUST be the the hair you need bro.
