My wife and I have not been the most loving couple the last 5-7 years of our marriage. Good core, but feel like roommates.

About 6 weeks ago, i found out she has been having a virtual affair with her first boyfriend, who she got in contact with on Facebook. I see all their messages and have been saving them. There are I love you's going back and forth, plans to meet up and have a weekend together, and even talk about blindsiding me with divorce.

I know I have been lacking in the attention dept with her (and vice versa), but what do I do here? Let it go and collect more data for divorce? Or talk to her about it? She says she cant leave me right now because she is a stay home mom and I am the breadwinner.

I provide, Im in good shape, and look good for my age. Not lacking tehre. She is 100 pounds overweight.
