This almost made me cry. Im in the same age group as you Ethan, [im 15....] and it seems all guys are like that [its nice to see at least one...you...not be a complete assbag....], If i was that girl, I would want to be warned about a guy like that. Even if he is your friend, he has no right to treat a girl like that. just dont be all wierd about it. just tell her once, and be sincere about it, and if she doesnt listen itll be her own problem. but if i were you, i wouldnt say anything to your friend, if he is a good/true friend you wouldnt want to ruin your relationship over a girl.
and about likeing her [well kindofsortof...
] if you really do, just tell her. seriously. the one thing i HATE about guys is when they like/dont like you and they dont tell you but constantly act like they like you. it gets annoying [esp. this one guy...dont even get me started...little assbag....] but dont try to downplay anything, if she asks especially. girls like guys who are upfoward with them..
oh and tell your friend to get some protection, because its not even about pregneancy, its about just having safe sex...what about deseases? thats the biggest problem. and he cant MAKE a girl get an abortion.
just stating my opinion, as a teenage girl who deals with guys [who sound similar to your 'friend' all the time...]
