How do you get a guy to leave you alone
You need to stand to your words your No should be No. Avoid him and cut all the communications. Do not show any interest in what he is doing or saying. Avoid being at the same place you can move away when he comes where you are.
Tell him strait up... Dude leave me alone I dont like you. And if that doesnt work tell someone.
Tell him your not interested and want him to stop bothering you.
