Oh dear!! You sound like my husband and I used to be, he isn't afraid of anything and is very black and white and hates it when he can't fix things.
Unfortunately after a few years of 'disagreements' I didn't talk about it, I pretended I wasn't in pain although cried and screamed in private which gave him the permission to pretend he believed me. This scenario continued for about 20 years which meant all that time my mouth was getting worse and I was in increasing pain, not eating, sleeping or smiling - the phobia was taking over my life.
In the end I had no choice but to do something about my teeth, my husband then became the best support I could have asked for and never left my side. He knew the list of things I did/didn't want and became my mouth piece for all the things I couldn't discuss with my dentist and his black and white approach meant there were no grey areas as far as the dentist was concerned - my husband also knew there would be consequences if he didn't do as I wanted
Truthfully, I was quite happy knowing my husband wouldn't make me go but it wasn't helping me. I just had to admit that his approach was what I needed, someone I trusted, gentle and honest but direct and supportive ....... I am now so grateful he did what he did as life is brilliant pain free.
Your boyfriend loves you and doesn't want to see you in pain and suffering which is why he gets angry and because of this is not going to let a dentist hurt or upset you .......
Talk to him and see if you can agree to your initial visit, let him become your protector.
It is a road full of bumps and you need to take baby steps but you can beat the phobia monster
