J.M.
I make a point to have alone time or spend time with my girlfriends! You have to!
It's tempting to take my daughter with me to run errands on the weekends just to avoid hearing my husband complain and/or because I don't like to give up any alone time I have with her (I watch 2 other children during the week), but when I do have the "privilege" of going to the grocery store or Target alone, I find myself in heaven!! Roaming the aisles actually price-comparing and browsing. Such a simple joy!
As far as hanging out with my girlfriends, I'd say I try to have atleast a lunch with a friend once a week or every two weeks. I have 2 friends that I meet with for drinks at Tijuana Flats -- we try to meet once a month at the least.
So yes, I do make sure to make time for myself. I never feel guilty about doing this because I know my hubby gets time for himself and, more importantly, it's great for him to have alone time with my daughter.
