Weird orrr??

Would it be weird if I dated a 21 year old? I'm 17 turning 18 in October and he turns 22 in December. I personally don't think so but my ex said something about it and a few other people. I'm very mature for my age, and already have a child. I want to be with someone mature and understanding, and he knows what he wants in life. So far no guy my age is like that.😂 He is such a sweetheart and just makes me happier than I've ever been.😊 Plus he is somebody I wouldn't mind my son being around eventually.
