Just remembered something (hey it was just over 5 years ago, give my memory a break!):
my compromise for the homebirth the first time (FBC in the end) was the HypnoBirthing. I would have done HB regardless, but DP didn't even want to pay for the Hypno course (he wasn't working at the time, but he had some other money tucked away). I told him that as I wasn't getting a homebirth I needed the HypnoBirthing as a kind of insurance for a peaceful birth, to align with how I saw myself giving birth. I told him that if he didn't pay for it I would ask my mum to pay for it. He knew it was what I wanted and I wasn't going to say "ok, I won't do it" just because he didn't think it would help or didn't think we could afford it. It was going to happen, no compromises. I'd compromised enough. I definitely credit my insistence on learning HypnoBirthing with two very peaceful births that allowed me to trust myself and my body to do the job it needed to do. Even if I'd ended up with interventions, HypnoBirthing was going to get me through with the best outcome for my emotional wellbeing.
So, yes, I've been to that negotiating table and pretty much told him what I wouldn't budge on and that if he wasn't on board, I'd leave him at the pier
