Some of these replies are ridiculous.
Slightly different, OP, because I was the one who went away but I went away to the other end of the country when my children were younger. My son was 8 and my I returned the day before my daughter's 1st birthday.
Until then, I'd been the primary carer - their dad worked full time and I'd had 7 months maternity leave and returned to work 2 days a week. But he did his fair share of parenting while he was home.
He had a great time with them. He was more than capable of being the default parent took them on days out, managed the house, made a birthday cake. I had a lovely week of peace and he enjoyed his time with the children.
We split up about 10 years ago. I only dated a few men in that time but 1 of them was childless (so obvs no children!) and two had 50/50 care of the children and were more than capable of taking them on holiday and managing that.
My partner now is nearly 60 and, when his children were young, he and his wife completely shared care of the children because they worked opposite shifts.
I can't comment on the OP husband but not all men are crap with their children!
I'd be more comfortable with him flying though if he's not used to driving - esp with such a long distance.
