I know that wives with kids, who have partners who are frequently absent, can get really really burnt out. Some women indulge in secret affairs just to have something "just for me." It's rather common.
I used to resent my ex-h, who got up in the morning, had his coffee, breakfast and shower unmolested, while i breastfed the youngest, got the other 2 dressed, broke up fights, tried to get them fed, all while my coffee sat on the counter getting cold. Later, if I was lucky, I got to take a shower with a kid or 2 in there with me... I got used to not even getting a daily shower.
Then he'd go off to work with other adults, even having lunches out, sometimes with a cocktail in the middle of the day! While I was home with the screaming meemies, eating mac and cheese, doing the endless laundry, etc. When he got home, he'd never help with the housework either. I tell you, it's no wonder I had no energy for sex back then.
Thank goodness we have polyamory, where tired burnt out mothers/wives can have that cake (something special "for me") as well as keeping their original loved partnership intact.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
