What Should I Do?

I've been friends with this guy for a year now and he told me that he's liked me for a while. I just ignored the fact that he likes me until a few months ago when he kissed me. He kinda just stole my 1st kiss... Ever since then things have kinda escalated. When we meet at the bus stop in the morning he hugs and kisses me. Whenever I do yard work for his grandpa's house, my friend tries to touch and kiss me. I don't know what to do. I don't want to tell him to stop because I'm afraid that he'll just get mad and leave me (I have no friends and my mom kinda dumped me). I like him a little bit, but don't want to date anyone until I feel that I'm mature and ready. I already told him that, but after I told him a few weeks later he started kissing me again. What should I do?
