AITAH for sterilizing myself against my partner’s wishes?

Ok Reddit I need some unbiased outside opinions because I truly feel like I’m going crazy dealing with this situation. I (28F) and my partner (28M) have 2 children together and have been married for 8 years, for those 8 years I’ve either been on birth control when we were preventing pregnancy or tracking my cycle when we were trying to conceive (adding this just to give the community the context that reproductive responsibility has always fallen on my shoulders). Recently we discussed the possibility of being done with children since we have our 2 and the family really feels complete, my partner is in agreement that a third child is off the table for him as well. So with that I thought “great! I can bring up sterilization for either him or I”, the reason I wanted this is because I’ve had every form of birth control before and none of them ever left me feeling 100% okay so I wanted to be done with birth control completely since we both agreed we’re done. It’s been about 3 months since our talk about more children so I brought up either getting a vasectomy for him or me getting a salpingectomy (removing my fallopian tubes), what I thought would be a productive conversation completely blew up. He outright refused a vasectomy and when I was okay with that and said I’d happily get a salpingectomy he completely flipped his shit on me, screaming at me about how he forbids it from happening and he won’t allow me to damage myself like that. I ended up just leaving the conversation and headed to get our kids from school but on the way I ended up calling my gynecologist to schedule a consultation for the salpingectomy after making sure I won’t need my spouse’s approval. So Reddit AITAH if I go through with the sterilization against my partner’s wishes?
