I met this one guy on whisper once. He seemed slightly creepy and even once told me he would give it to me hard. We talked a little and I thought he was okay but the initial meeting creeped me out. He kept pestering me to meet up so I finally said let's go to the park where there is people. We hung out a few times and I started to think he was cool. Ever since we met he had been offering me rides to hang with him, which I turned down all. I haven't hung out with him for awhile, he responded with being slightly needy. He then asks me if he can pick me up in order to spend time with him at his brothers house. I am 17 he is 20. What should I do?
