My guy won't let me end the relationship, what to do?

I've been seeing a guy for 3 months - he pursued me as I wasn't that bothered in dating anyone. Now the relationship hasn't developed. It is boring and he doesn't seem to have any ideas of what he wants to do when we are together and I en up planning everything. Thee is also not enough (he is happy to have it once a week and doesn't push for any more). I have told him there is no future in it and that I am happy to be friends. The is phenomenal and so we could maybe have that now and again, but I cannot be loyal to him as I need other things and people in my life. I have been quite honest. Twice I have said this (in increasing severity) and he just cries, lots of tears and says that he doesn't care he loves me and wants me and doesn't care what I do. I think this is wrong, he seems to be a nice guy who needs a nice woman to love him (I told him that) and that person isn't me as I am too lively and wild. He says he doesn't care what it's called he wants to carry on with me. I cannot act like I'm single whilst I know he depends on me emotionally, it would seem wrong, so I feel trapped by his clinginess. I will not hurt him by being ruthless and cutting him off, it would hurt him a lot, so I am just repating my message to him over and over. I hope he will get it and let go. Is this right? I am 40+ but naive with these things.
