Girls - If a guy likes you but u dont like him and he tries to kiss u - how will u react?

also shud the guy apologize afterwards? i tried to kiss a girl i liked and she moved back and I said "I am sorry. I really like you but it's okay if you don't feel the same way. I am really sorry and hope that we can still be friends." Was that a stupid thing to say? wat's the best thing to say under the cirstances? i m not really friends with this girl (met her in a college cl and asked her if she wanted to study together and this was our third time studying together) but i want to become her platonic friend if not her ual boyfriend.
