Reconnecting after major life changes

My husband and I have been together 11 years, and married for 4. Our baby is almost a year old and 3 weeks before she was born his 14 year old son came to live with us full time after his mother’s mental break down.

I am having a hard time readjusting my relationship with my husband, after going from a couple to a family of 4 with no private time in a matter of weeks.

Most weeks he works 70 hours a week, most nights working until 9pm or later. My step son stays awake until 10:30, and my daughter wakes up at 4am every morning.

We went from having every week night to ourselves and 1 entire weekend a month to enjoy each other. Now we can’t even have a conversation with being of heard.

What small things can we do to bring the romance back?( he doesn’t even want to have sex when his son is home). I’ve asked him to have his parents have his son sleep over one night so we can have a “date” after our daughter goes to bed, but they will only watch him if my husband has to work at night.

Sorry if this comes across as whiny,but I can’t shake this feeling that we are drifting apart
