Advice on a situation

Hi, I’m gonna start off by saying that I’m 16 about to be 17 in September.. Ok so about three months ago I was added in this group chat with friends of a guy I knew, I started to fall for one of the guys in the group chat! So we started to talk and I really really like him, so he’s 19 about to turn 20 in September. I want to start dating him and have a good relationship because he’s unlike anyone I’ve ever dated. So I need advice on how I should tell my mom about him! She’s super strict and to me age doesn’t matter! Also i Want to go visit him because he lives in a different state, so if I tell my mom maybe she will let me.. So if anyone can help me please comment below!
