Not bad advice, but a caveat: don't become her shoulder to cry on all the time. Be there and let it be known you're supportive, and be nice and all, but don't become the guy who she tells all her relationship problems to. Life isn't an 80's movie, and it's certainly not directed by John Hughes. The goofy male friend who's there to listen to all the girl's problems rarely gets the girl.
