I'm gonna jump in here, guys, with a female perspective...hope thats okay. I have suspected that my H is having an A for a long time now. There have been a lot of things that have happened to point to an A. However, every time i ask my H about it, he denies it. Thus, i've stopped asking. I have thought about this and there is a part of me - a big part, i think - that wishes i did know for sure, and that my H knew that i knew. I feel like it would just put everything out on the table. My sitch is a little different in that my H and I have been separated for over a year, and the legal stuff has been started. But, i do wish that i knew for sure...at least then he could stop lying to me, which i think is the worst part. My H told me that i needed to make the decision on my own as to whether or not i should hang on. Well, thats fine, but i do think that i need to know all the variables in order to make an informed decision.
Anyway, thats my 2 cents...thanks for letting me vent it.
