We started texting yesterday and everything was going good. I told him that he's too old for so I wouldn't go out with him but if it wasn't for the age gap... He seemed OK with it. Today he kept saying how pretty I was and that he wishes he could be my boyfriend. Also that he wouldn't find another girl like me. I tried to tell him that there would be other girls but he said you but they won't look like you. This kind of freaked me out because we barely know each other. So I changed the subject but then I just said I have to go do my hw because I didn't feel comftorable texting him anymore. The whole thing made me not really like him anymore and I never really liked him that much anyway. So what should I do??

Be honest with him, and tell him to leave you alone, and then start ignoring his texts.
