My husband works for his family business, 3 minutes away. We are so blessed that we can live near where he works, yet live in a nice place. We live in a small town, about an 1 1/2 hours from DC. We see him in the morning, he comes home for lunch 4 out of 5 days, and is usually home by 5 in the evenings.
There are always challenges though... Because his name is on the sign, so to speak, he brings his work home with him; works on his computer or phone. He gets calls on the weekends, and if there is a problem, he usually is involved in the solution. He also travels for work, too.
We also live on a farm, and we are constantly improving structures (working on a shed roof now), making hay in the summer months, or taking care of our animals. Some of these things the kids can do with us, usually they are around us playing outside.
So while hubby is close most of the time, his time at home is not always a planned activity to entertain the kiddos. Sometimes it's just being "around".
I am a firm believer that it isn't about the amount of time the kids are spending with dad, but about the quality of that time. It sounds like, though many of that dads mentioned here are not home a lot during the week (when the kids are awake), they are available, and doing their best to nurture their children with the limited time they have.
We mustn't forget that our husbands sacrifice their family time to provide for our families, which is very possibly the top way that they, as men, show their love.
(***I don't agree with Donna S. I thought it was a little judgmental. There are always pros and cons to any decision you make, and it sounds like it is one that you and your husband are considering while weighing the options and repercussions. You'll do what's right for your family and make the best of it! Good luck to you!)
