Please... Please... Please... don't string him along with this fake as "Let's just be friends" bullshit. No one buys it any more. Either you want him or you don't.
You might want him as a friend, but seriously, he doesn't... he wants more and always will.
This is exactly why exes just CAN'T/SHOULDN'T be friends in my opinion.
It creates too much shit.

Write down your feelings, so you can make them clear and in a way that will make him understand and hopefully not hurt him. Sit him down and talk to him, tell him why you don't want to be a couple and how you're better off as friends. He might not want to be friends right away, he may need time to heal.
