Girls nite out

 A little background.  I am the mother of 3 boys.  I work 3 days a week, one day a week I go to my husbands business and work there and the other day I take my mom to do all of her errands.  So basically I am out of the house 5 days a week.

My husband leaves by 7 am and doesn't come home until 9 or 10 most night.  We own a business, 2 mortgages, you name it.  So he works his butt off, but so do I, I just don't pull in the big bucks.  On Friday nights, he goes out with the guys.  I'm fine with that. 

Then there's Saturday night.  That's girls night out.  Whoooo  hoooooo!  Hubby works Sat. too, so I usually don't even get out of the house until 8 or so, and let me tell you, I have to make a serious effort to go out at that time after being home with 3 boys.  Oh..they are 16, 10 and 9.  But I do go out.  Usually we only go to one of the girls houses that doesn't have kids, or the kids are not home.  Sometimes we will go out for a few drinks, or dinner, or a comedy show.  I really look forward to this, and it seems to "ground" me for the next week.  I have more patience and feel like I had some time to myself.  When we don't meet up on Sat, I find that I am very cranky the next week

Some of my friends are jealous and some just can't believe that I am so "selfish" to get out one night a week without my kids, let alone my hubby.

So, my question to you, my gather friends...do any of you do this also?  Am I being selfish?
