Is it wrong?

Is it wrong? one day at a time: I started dating even though I know I'm not ready for a Relationship - I have been honest with the guy and he says he understands, but I can tell he's getting really attached (we've been friends for awhile) and I feel like he's only going to get hurt.  Should I stop messing around with him, even though I've been honest and told him I'm not over my ex?  Or should I leave it up to him to decide if this is okay for him?
Re: Is it wrong? tyrogers: Do you want to save the friendship?
Re: Is it wrong? ColoHill: You said you've been friends for a while...Well I say if he matters enough to you, and you know he will probably get hurt (even if he tells you he won't--we lie to ourselves sometimes) you should probably call it off.  Just my 2 cents...
Re: Is it wrong? tyrogers: Yep.  If you want the friendship to remain.  Cut all sexual/dating/romantic ties now.

Re: Is it wrong? one day at a time: Thanks everyone - that helps.  Yes, I do want to save the friendship.  We have called it off before (my doing) but then we mess around anyway.
