why don't you live at home anymore? Who told you to move out? Did you make that decision or did she?
Move back home, it's only been a few days.
Attraction is an issue here, she isn't attracted to you anymore, it's very obvious. It has nothing to do with another man or anything like that. You exhibit behaviors that aren't attractive. Did you read your first post, look how many times you mentioned how much time you spent on this & that, it's very analytical: do you do this with her? Do you mention everything you do?
Validate her feelings if she ever chooses to talk to you. If she isn't in love with you, you tell her that's unfortunate. If she says that you're jealousy is too much, tell her you agree with her, you have a jealousy problem. Stop dealing with this problem using your male logic, she's a woman, she uses female logic, it's different and the two don't work well when the ideas are different.
Move back home, it shows that you are confident in yourself and that regardless of what she does, you will be fine. She may not like it at first, you may make her angry but too bad, it's your home too, and you will live there until it is sold or split up in a settlement. Setting boundaries and standing up for yourself will generate respect at her end, even if she realizes it or not.
Stop analyzing what she does, stop talking to her, stop asking questions, stop doing everything you are doing, seriously.
Get a !@#$% life, sorry, that's blunt but you just seem to be focusing to much on her and what she does, and thinks & feels. I know it's tough bro, but the sooner you actually get a clue on how this is going, the sooner you will achieve some peace in your life.
Implement no contact with her or limited contact. Stop texting her, calling her, emailing her, etc. Don't initiate any calls, txts, emails of any nature. You can reply to them but take your time but make sure it isn't 1 minute after receiving communication from her.
Stop looking at her and trying to reason with her, that won't work. Regardless of how much you want to work on this, she's at a point where she is frustrated and at the end of her rope and you aren't helping anything by pestering her with R talk. Women are more intuitive than men, she can sense that any attempt from you to talk to her is about getting her to come back and want to work on the marriage. Get a life, go dark, limit contact and start living your life and definitely move back home.
