I think Amy's advice is the best there is to give. For your friend, let her know that you'll support her whatever she chooses, and that you'd happy to help her make the decision if she asks (by, for example, going to the doctor with her).
As for the guy, obviously it's your call and this is only one incident, but I wouldn't really want to be friends with someone that selfish. Maybe he's really just handling this badly and he's overall a nice person, or maybe these are his true colours. It's hard enough to tell in person, so I'm afraid we're not likely to be much help there. Try not to burn any bridges too fast, and exercise your judgment as best you can.
My best wishes to your friend, and do suggest that she can come here if she wants advice or support of any kind.
The atoms that make up you and me were born in the hearts of suns many times greater than ours, and in time our atoms will once again reside amongst the stars. Life is but an idle dalliance of the cosmos, frail, and soon forgotten. We have been set adrift in an ocean whose tides we are only beginning to comprehend and with that maturity has come the realization that we are, at least for now, alone. In that loneliness, it falls to us to shine as brightly as the stars from which we came.
