lfm, we all understand the emotional swirling that you must be feeling.
denial of what is happening, that you are being betrayed by your should mate, that everything you have been building could be stripped away in a flash...this is not easy.
you are trying to find a way t9 snap this back to the way it was. here is a hint for why that won't work...first she doesn't want to right now and seriously things weren't as good as you think, we're they? something was not right. THAT is what you need to focus on.
yes, the house is coming fast, thst is not a time line that you can expect to work with...too fast.
you have been with this woman for over two decades. that is a long time and it will take a seriously long while until lasting changes can be made. so you have time here to search your soul and really get to heart of your issues.
but as nuts has mentioned, as well as a few others...you have t9 decide what your boundaries are and what you will do.
does your consequence HAVE to be divorce, ultimately it may. do you want to be divorced? is that your ultimate goal here? are there other things that you can do to show your wife that you are no longer going to tolerate the open disrespect?
have you spoken to an individual councillor yet. IC can be a good way for you to work theough your boundaries. if they are not willing to do this, find one thst will. ic is not a one size fits all.
