It just sounds like your work schedule is killing your sex drive. How many hours a day do you work and commute? Are these long hours temporary or permanent?
I had 3 children in 5 years and they were not good at sleeping through the night, and also were constantly crawling all over my lap when they were awake. I was a full time mom. I spent years being tired and feeling touched out. And nearly sexless. Things changed when my youngest child turned 5 though. LR has kids and grandkids living with her, so her saying she hasn't had sex in 2 months does not surprise me.
Can you make changes to get more sleep? As Dirt said, get more help with chores around the house? Our bodies require rest more than sex, so when your physical stores are depleted, the sex drive is naturally going to plummet.
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
