Is my son to old to still be sleping w/ me?

I am a single mother with an 8 year old son who still sleeps with me. Brief history - I have been single since he was born. We lived with my parents for about six years after he was born and he had no choice but to sleep with me. When we finally moved into our own apartment, he slept with me for a while but then eventually started sleeping in his own room. Now that we moved into our house, he has slept in his room a few times, but most nights he sleeps with me. He has said that he is scared to sleep in his room by himself, but he is also afraid that he will lose me. He is in many activities, and he is confident. He doesn't like me to call him baby or treat him like a baby because he says he is a big boy. And he is not a timid or scared child. He's not scared of new environments and he adjusts well, he is not scared to be alone in the house if I am outside, etc. I know he should be sleeping in his room, but I don't really see this as a problem. I am not married and I never allow others to spend the night with me. My friend says I am causing him more harm than I think. Any advice?
