I need help!! Perferably from a guys view point!! ?

So im talking to this guy Richard. Hes almost 2 years older than me. I really like him but idk if i should. He never says in pretty,beautiful,sweet,ect. He only texts me about dirty stuff like sex and he wants to do me. I told him i like him and he said he liked me too but idt he does. What should i do? Forget him and move on or stay with him??
