I think mentally you are in an awful place. You are stressing about a relationship as if it was the zombie apocalypse.
3 weeks ago you were trying to get her in bed. 2 weeks ago you asked her to leave cause she wouldnt get in bed. now you are bouncing between noticing unobtainable single moms and unobtainable explanations for why your wife does something.
maybe she is doing it just to mess with your head to see if you flip or flop this time. maybe she is scratching her head just like us wondering why you cannot be stable with your emotions and tought patterns.
now you "impatient" awaiting, hoping this "neutral" 3rd party can solve the problems you should be able to solve yourself. What if they say, "your wife should move out and find herself," are you going to tell us this MC was awful because they repeated what your wife has been telling you all along?
