What am I doing?

My girlfriend absolutely loves me and she loves spending time with me. We planned on going to third base but all of the sudden i chickened out because her mom talked to my mom and her mom said she didn't like the idea of her having a boyfriend (she doesn't know we are going out)! She said it was okay with her if we didn't go to third base cause she could tell knew i was nervous. PLease dont say all the stupid stuff like "how old are you?" just give a answer to this, do you think i should be the best boyfriend and go to third base or i should just Best boyfriend without third? I know that was a stupid ques. but I'm confused.
