3, I just started following your thread. I'm a soon to be mom of two boys and am in my early 30s. H also has OW from work. Thankfully that OW is still in Afghanistan (I think).
Anyway, I just wanted to commend you for not telling everyone about what H is doing. I told EVERYONE. Even my neighbors dog knows. I wanted everyone to know to shame him. You are way more mature than I have been.
