Strong,

do not look for signs from her. I know buddy, I know you are grasping at straws, trying to find that ray of hope, but your time would be better spent taking care of you and your little guy.

Also try to stop with the spying, because it gets you all worked up. It gets your mind racing 100 mph going in all the directions at once. You found out she is 2timing, so stop now. Stop for your own sanity. Look at it this way, 2 things can happen if you snoop:

a) You find out she really is getting physical with this guy. How is that helping you?

b) You get no definite proof. However, the absence of proof of an affair is not the proof of absence of an affair.

In her mind, you are gone from the equation so you holding your breath every time she sighs is sooooo unproductive.

Stay strong buddy...
