I am a guy so I would know. First of all I have been disgust by a lot of girls so if he looks at you in a wierd way or just makes an escuse or something like that you would know.
You could flirt with him until you know if he is single and interested in you.
You know that he can't. No Guy who has never met you can love you truly.
Meet them in real life and find out. Just watch their behavior for signs.
If he's still hanging around or dating you then he still likes you.
he like you
You know you have met the right guy when you can be your total self around the guy. He makes you laugh , and sometimes cry but in the end he's the only one you think about , and your heart has no regrets just love. Answer You will feel totally different than you ever have before and you have no interest whatsoever in any other guy. You will feel amazing.
Talk to the guy, and talk to your dad about this guy, not in a way that your dad will get the impression that you really like him just as a friend you just met or is getting to know. Talk to the guy, not in a firty way. Just get to know him. Or you would ask one of your friends to talk to him for you and tell him what you think of him. ;}
get 2 know the guy more.
no
Does he really need to know this? You can just say you didn't know they were enemies and it was before you met him. There is nothing else you can do.
Do some research, find out if he has a girlfriend.
he looks in your eyes
