Will this change out relationship ?

Does any of your boyfriends / husbands / partners travel for work ? Are they gone for a long time ? How has that changed your relationship? Has is affected your relationship in a good or bad way?

My bf lives with me. And we have a great relationship. He was offered a job where he would have to be away for 2 weeks and then he would be off for a week and back home. He’s thinking about it. But I’m scared that it’s going to change our relationship 😞. I really don’t want him to leave that long.
