Hiring a Doula

I’m about 8 weeks pregnant and I already know I’m going to have a hospital birth with an epidural. I did my research on Doulas and I’ve decided having one would be really beneficial to the birthing process. My fiancée however feels otherwise. His words are “it’s an extra expense for someone to make you think you feel better” and it’s “a waste of money”. My feelings are hurt that he didn’t even do the research to see why I feel a doula would be good for this process. Just that he thinks it’s dumb and refuses to pay for it. Has anyone else had experience with this? Or used a doula when people gave an adverse opinion? I’m torn.
