I'm in the same boat. My 7 year old son hasn't overheard anything other than arguements, but he's on to something being not right, mostly because my wife has stopped being demonstrative towards me (she dropped the bomb on May 1st). Now, I have started DBing since then, and things have gotten a tiny bit better since then, but the repercussions are effecting my son. He's developed a nervous blinking habit that gets so bad sometimes that his teacher called to ask us about it. I'd hate to think how he'd be if we split up. He's a very sweet and sensitive boy, and he'd likely be crushed. 90% of my effort to save my marriage right now is coming from my love for my two boys, because right now my feelings just aren't their for my wife (but I'm working on it - I'm doing the "Act like your a loving spouse until you really are," technique, and strangely it actually works.
