I'm bumping again to get a plural answer to "Should I reciprocate affection if she initiates?"
I don't know what to do, or what are the pros/cons of that in my situation that you all have followed.
Very simple.
If you are to have any chance to savage this marriage you need to stop YOUR needy behaviors as soon as possible. Acting desperate or needy is probably the MOST common mistake guys make in these situations. It is the ultimate attraction killer.
NEXT. Take 30, 45 - 60 days of NO CONTACT. You have been dumped. It would be ridiculous to think your wife doesn't think you love her. She knows that. That is not the reason she left you. She dates other men and you still tell her you love her. Talk is cheap. You need to come up with a plan. You have no plan. Take a month or two decide if this is someone you really want to be involved with. Be able to answer those questions for yourself before you are in the situations where they may be asked.
3. Start dating other people.
And quit the arguments. If you want to have a postive relationship with someone dump the negativity. Spoons, cookware, pecks on the cheeks are not valid reasons to fight. As you go through this list you should notice that all 4 of these simple suggestions are related to eachother. If you don't know what to do the first place you need to start to answer that question is to Know Yourself. The rest begins to fall into place after that.
