Maternity Classes vs. my husband

Shyla • I'm 29 and a stay at home mom to our 9 month old daughter
I will apologize in advance for this rant but I needed to get it out there. My husband has absolutely NO interest in attending maternity classes. We have had 3 so far and I have gone to two by myself. The only one I got him to go to was Infant Life Saving and he still wasn't thrilled about it. We still have to have our 6 hour childbirth course and then 3 more birthing classes for Natural/Water Birth. I told him that these are really important not just to me but so that he knows these things as well. He just blows it off as no big deal. It's really frustrating being one of the only people in class who doesn't have their significant other with them. 
I think this is most frustrating because I have been super emotional lately and as the pregnancy goes on I feel like he's losing interest in everything. Ugh....I just had to get that out.
