Is it normal if I've heard so many hurtful and rude things from my boyfriend that if he says anything hurtful now , I don't care?

And I think I don't feel anything for him now. In my case , if someone hurts me consistently then at some point I loose feelings for that person. I forgive that person but can never forget those events. Is it just me? And he even says commitment is necessary in every situation.
