OK, so you now know that there are other guy(s) she is innappropriately conversing with, and it's crushing you. A lot of us don't or didn't believe things would come to a point like this, but unfortunately, it does happen. You're not alone.
Now, from hereon with this post, let's talk about YOU. What do you like to do? What have YOU been wanting to do for a long time that you haven't gotten around to? What kinds of things do you think you might want to try? What did you used to like to do that you haven't done in forever? Got a couple old buddies you have lost touch with, who you can call up and (important) NOT discuss in any kind of detail your situation with....rather just go be a dude for awhile.
I would like you to answer this question with your next post, I think it will be good for you. Do not mention your wife in any way in it. Let's talk about YOU!
