My fiance and I caught his dad cheating... His "date" tried to sneak out through the back as we entered the house but we still saw her. He thinks it's okay because it's "just physical" and he loves his dear [third] wife (not my fiance's mother) very much. By the way - it came out that his wife had/has cervical cancer and therefore they can't... you know - hence he needs to sleep with this other woman to relieve the "urge".

I used to look up to this guy a lot, seeing him as a "second dad"... now I can't stand being under the same roof as him. Every time I see his wife (whom I admire and respect dearly!) I want to tell her, but I know that this is none of my business and I should stay out of it.

How the heck am I supposed to cope with this? Cheating is one of the few things in life I hate (having been a victim of it myself some 5 years ago), but I can't just write this man out of my life because he is my fiance's dad, after all. So how can I just bring myself to be civil to him - for my fiance's sake? (For the record, I'm not good at hiding how I feel about people...)

Sorry to hear about your predicament. Sounds like a terrible spot to be in...

How does your fiance feel about all of this? What does he want to do about it?

He's hurt and upset, of course... We stopped talking about it for now, but he made me swear I won't interfere. Which I'd pretty much decided already.
Now, if only I could forget it ever happened so I can at least stand to be in the same room with him again...
