If ExW wanted separation/divorce I could not stop her, but I was not going to let her actions be an excuse for me to break my vows. It's not about positioning her to be the bad guy, yet getting the result you want; it's about standing up with integrity to do what was right for me and my kids and honoring the vow I made. We can't control what are spouse does - hence I'm divorced - but we can choose to act with integrity and do the right thing regardless.
So BL do you believe that no matter what a spouse does you need to honor your vows? Don't you think it might be better to honor your values? Is sharing your W with another man part of your values? If you married again will you have any boundaries?
