Relationship sex and birth control

I've been in a relationship with my guy four years and have two kids 7yr son and 6months daughter I was on the depo shot since I had my son. I tried to get back on birth control and hate what it does to my body no matter what I've tried I don't want to be on birth control anymore and he doesn't want to use condoms but don't want anymore kids. I feel like I'd it happens it happens. Am I wrong for not wanting to do birth control to make it convenient for him?
