BF travels for work OT

My BF often goes OT for work and often times he is away for a week, I have never dated a guy who needed to work OT for work so I'm still getting used to it. We are in the process of buying a home and TTC so I trust him wholeheartedly but idk if I could get use to this. Have you found yourself in this situation and if so how did you deal with it?
