My husband travels often for work too, although he only takes on traveling if he absolutely have to. As women, we tend to hide our feelings for fear that it is not justified. But it’s super important to have communication in a marriage, it’s tough that u all are not living together. But I would suggest to let your husband know how you feel, but in a manner that makes it sound like u want to solve problems together with him, not necessarily blaming him. He might not know how you feel too and important to let him know, I’m sure he would care!
