How do I not let this control my every thought?

Why does the sadness continue to come back at the worst times.
I only found this site a few weeks ago, unfortunately. Basically, only started detaching the last two weeks.
I just had the best weekend with my kids yet. Now I'm sitting here and I'm just f-ing miserable. This house is so quiet it's not even funny.
I know it's only been two weeks, but I haven't even seen the hint of a chink in her armor. Of course, if it's in her face I wouldn't see it because I can't even stand to look her in the eyes. I go to get my boys or she comes here to pick them up and it's "Love you, boys. Be good for Mom. See you Tuesday." then it's back to the house. It hurts to have the woman you love more than anyone in the world besides your kids, do things to you that makes you feel as if you can't even look her in the eye.
But, damn, her legs sure looked nice and long and tan yesterday. LOL.
I've done pretty good the last couple weeks, just feeling low and sorry for myself today. Maybe it's the housework and job work that is looming that I have to eventually make myself do that is depressing me more today. It's almost noon. I've been putting them off for a few hours now.
Hope everyone enjoyed the first big summer holiday weekend. I know I did.
