Aw man buddy really wish I could read your response! Hope they fix this issue soon...
Lets try from a computer....
You had mentioned that in your confrontation you were going to explain that her affair is "not going to be tolerated". Im trying to understand what actions you are going to do that will back that stance up.I dont see how living as roommates is showing that you "arent tolerating" her affair. Saying that you arent going to be a part of a three person marriage isnt a great way to evict the affair partner - it's about stepping out of it yourself.
Are you prepared to make that step? Not just emotionally and mentally, but physically and financially...
