Have I fallen for my casual sex partner?

I met this guy last august through a friend and we hit it off we exchanged numbers. At first we would sit outside my house and talk and kiss then I'd go out with him and his friends. I started going over his house and we would just cuddle no sex this happened for about 5 months and then we started having sex. A first it was whatever i never caught feelings and i would go o ver hin house 3 times a week nd do it until about 2 months ago i starter catching feelings. Ive hinted at it that i caug feelings and hes pickedup o. It but never asid anything. Should i cut him off completely or idk what to do. He makes me really sad because im not with him. I sit a home and get depressed
