Hi and welcome
My husband is typically gone for weeks at a time as well; When he started back in 2006 I was working FT, then got laid off, and wasn't working for a short time, but that made the 'in between days' much longer, so went to PT work at least; I found that keeping BUSY does help, either at work or with the animals (we have horses,dogs and cats), I even started my own horse training business for a time; I am now working FT again and it does keep me somewhat sane, lol. You could also do volunteer work someplace, or maybe get involved with a church; something else I did a few times was go OTR WITH him, I was able to see firsthand what its like out there for him, plus I learned a lot about my OWN driving habits by watching how others drive around the bigrigs; you will see a lot of cool places as well, meet different people, etc. No doubt trucking is tough on a marriage/relationships, these are just a few things that have helped me out along the way, good luck to you
