What is up with thiss? helpp me ppl!?

I like a guy that is 18 but i am only 16. My mom approves of us dating, while his mom thinks we should wait another year. His mom even called my mom to tell her she doesnt want us 2 dating yet. she also told my mom that he has really bad hurt a lot of girls he has dated in the past and that she doesnt want me to get hurt. The way i know him, i dont think he would do that to me.. but now i am kinda scared. i dont wanna be hurt again at all. i am changing my life for him.. and i am scared i am making a mistake. i dont wanna underestimate him..he doesnt seem like that kinda guy to me.. i wonder if his mom was saying that just to scare me or something. cuz she really doesnt like us dating. I dont know how to deal with his mom.. she is the type of fake nice to me and i hate it.. i dont know why she doesnt like me.. ive never done anything wrong to her. i really like this guy and i think he likes me.. but i dont wanna be 2 sure about it..if anyone can help plz answer me backk... thankss much
