"My revelation is that she sees me as weak and unnattractive because I have not been able to set boundaries or stand up with myself for her and lots of others."
How do you know that? Did you ask her? All of that stuff about seeming weak, etc. flies only to a certain degree. You should be standing up for yourself already. That includes doing what you want to do and becoming the better man because it's what you desire to do. Not because you think it's what your W wants.
"I feel and that I can't stay living here if she is actively dating and I cannot afford to pay rent and mortgage so we have to get rid of the house."
You notice how you end up doing what she wants any way? Do you want to get rid of the house? Have her come up with a solution. What do you want to keep and have? Start thinking of your needs.
