Right there with you.
My husband travels from Monday to Friday,and sometimes study and takes test in here (NJ) Saturdays half day.
So I drop him to the airport on Sunday after 4pm and pick him up on Friday night, then Saturdays only see him half day!!
It wasn't always like this, when we just got married he worked from home (he is a computer guy) so we see each other 24/7.
I didn't mind much because, well, we were just married, lol.
Then after a couple years he start working some times home some times traveling, that was my favorite time.
Then he lost his job, and many things happen that we end up losing EVERYTHING, it was really bad.
Well, we had a angel in our lifes, she not only gave my husband work in her school but the best she let him take computer test for free, salary was little but the test for free were a bless that help my husband to grow very fast.
In a couple months he start to have more and more calls for work, all out of town, until he got hire for a big comapny and he travels now all the time, and he still help our "angel" on Saturdays and she still let him take test in return from teaching some classes for her school.
I tell you all this because the reason I don't go crazy everytime he leaves is because we were so under the water with 2 kids that now we appreciate every work that comes.
He calls me often, and I hate being in the phone but I try anyway, he has a camara an he can see us all the time (I know is freaky and sometimes I turn it off when I need to) we talk for sky, we text a lot.
He spoils us when he is here and we got "every" Friday night to the movies, just him and I.
He is my best friend, he knows me so well, and he is a great guy, is never being a day in our marriage that he doesn't tell me he loves, those details help.
We pretty much gave up almost all kind of social life on weekends so we spend our time as a family.
Even after all this, it gets hard and lonely many times, and every once in a while we wonder if it is worth sense some times I feel like we never see each other anymore and he misses so many things of the kids, and while the 13 year old understand better the 2.5 often ask for him :( I takeons of pictures and videos for him.
But we always think that we are doing what we need to do, and we recognize that each other works hard as individuals for the good of the family, and hopeful soon we would be able to slow down again, or I can start traveling with him.
My only advice: keep the communication any way that works for you, spend sometimes alone as a couple, take tons of pictures for dad, talk a lot to your kids about dad, appreciate each other hard work and keep your self busy (you will find me here a lot, lol).
