Spouse working 3rd shift.

Montana

So it's been a while since I last posted but this came up in my relationship and not sure how to handle this. It's that I work first shift and now my fiance has a 3rd shift job. It's that we are as well ttc. But ladies whom have a spouse that works 3rd shift (graveyard) how do you manage in the beginning? It's that I'm having a lot of fears over it. For example that it will cause a lot of arguments between us and it turning to hate, 2. Him getting into an accident trying to drive working late until sun rise. 3. He will be less willing to help me around the house etc. Or any advice. It's that prior to this relationship I was in a relationship where he worked 2 and 3rd shift at the company he worked for and it turned straight to hate and being divorced from him.
