I completely agree. My H does the same crap. Every weekend is awesome. To see us, you would think we were a normal happy family. Come Monday, not one call, not one text UNLESS it involves our S or house related issues, bills, etc. By Thursday, the affection is making a come back.
So it's hard, but I just try to maintain throughout the week.
I try not to analyze but it does make me want to scream. Mondays, Tuesdays and Wednesdays, I want to shake him. So I just look forward to Thursdays and the rest of the weekends and concentrate on other things the other days. Very hard but I'm trying.
I'm so glad your trip was good. You deserved it.
