In between a rock and a hard place about riding over the road with husband

My husband and I owned our own business for ten years. The recession took care of that so he decided that he was going to drive.

He started out as a side dump driver which was great. He was home and making OK money. In the mean time I became a temp. I have been at the same job for a year and a half.

Now that our youngest is graduating he would like me to go out on the road with him full time. This scares me. I have gone on a couple of trips and the driving doesn't bother me. It's the not knowing of when we may get home that does.

Granted there will be no weddings soon but they will happen and I have not missed a single milestone in my girls lives. I don't want to start now.

I am also scared of resenting him if this doesn't work or when problems arise as we all know they will.

I don't know what to do. Any advise?
