~Advice needed/appreciated~

I have a problem. My ex-boyfriend says he wants me back, and I've had three other people ask me out (at about the same time), and another couple of people tell me that they like me. I said yes to one of the guys, yet now I am having second thoughts. Should I tell him that? What should i do about all of the other guys? what are your thoughts/opinions?

I have thoughts and opinions, but I need a couple of questions answered first, if you don't mind. Do you still have feelings for your ex-boyfriend? What about the guy you said yes to, do you actually like him? Do you like any of the others who asked you out?

Um...i want to keep my ex boyfriend as a friend...The guy I said yes to has been a friend for a long time...i thought I liked him, but now I am not sure...It just feels strange, if you know what I mean. I like a few of them, but I don't know...

You like a few of them? You're more confused than I thought. I don't suppose you could explain this either?
