Hi Renee,
My heart goes out to you. I really hope it all works out so that he can be there. I know what you mean about being worried that you might feel resentful if he does miss the birth, and worried how that could impact your relationship. Maybe when the time is right you could talk to him about that? If he knew how much you would like him to be there, and you could hear him talk about other ways that he wants to put you and your relationship together as his highest priority, you both might feel better. Relationships are so tricky, aren't they? I also would suggest a doula, because even if he can be there, (and I hope that works out), a doula would be a great addition to your birth support team ,especially as it's your first - with your mum, your husband and a doula as well you'd have top support. A doula is also an angel with skin on to have around in the first days and weeks after the baby is born, they really help make the transition to motherhood smoother. You deserve top support, every mother does. I know Perth has some fantastic doulas, and often student doulas will attend births only charging a nominal fee for petrol etc.
