Natural birthing class

So this is our 3rd baby. The past 2 times I’ve gotten an epidural. Well the last time I had bad back pain for awhile after because of it, so this time I want to go all natural. I decided to meet up with a midwife and do a serious of natural birthing classes. This is the 1st time my husband is available to go with me and he’s refusing to... he just keeps saying how there doesn’t need to be a class to push a baby out. I’m trying to explain it’s more about relaxation techniques and different pain management skills so I don’t get the epidural and he’s just being an ass about it... I don’t know what to do anymore.

This was mostly a vent but if anyone has any insight on how to help the situation it’d be appreciated
