Not enough time

Natalie

So my fiancé and I have been trying to conceive,but recently he started a shift at work where he goes in earlier...which means he’s in bed earlier since we live an hour away from work. By the time I get off work and get home he has to go to bed, and isn’t willing to have sex. I dont know what to do because whenever we talk about it or having a kid he blames it on me that iam lagging and then a huge argument erupts. Any advice?
