I need to get this off my chest..

So I'm dating a black man who is two years older than I am, I am 14 and he is 16 but my mom doesn't know and her and I had a talk the other day and she seemed like she didn't want me dating anyone other than my race (white). I just wish my mom wasn't so strict about who I date. I love my boyfriend and I literally have to lie to my mom so that I can hang out with him. I just wanna tell my mom that I am dating him but I don't want her to be mad at me... can someone please help me with this situation? I just wanna be able to go out with him without having to be scared my mom is watching every movement we do.
