BF working away from home

Megan

My BF is potentially looking to work away in the Netherlands with his work, Im not sure for how long ATM. And I'm just concerned. I obviously want him to do well and succeed but part of me is worried as of what if he meets someone else etc. I wouldn't be worrying so much but recently I have found out my dad has been cheating on my mum and he works a lot away from home too and its jist made things worse. If anyone can advise on me on how to deal with this sort of change as we have been together 2 yrs in November and I feel like we haven't done much as a couple before he goes away. Thanks x
