Friend in Denial..., And it's bugging the crud outta me... Options

[HeroesAndVillian...]

Ok, A friend of mine was with her boyfriend for about a year then broke it off (on V-Day) and then got back together with him after a few months of begging him to take her back. A few weeks ago, she gave him a handjob and somehow got the idea that just because her period didn't come on the exact day she'd marked on her calendar that she'd gotten pregnant and told her mom. ((She's 16 and he's 18)) So her mom flipped out and everything but he didn't go to jail or anything. He freaked and broke up with her because he doesn't want to go to jail and wants to do more but with her anything they'd do would get him sent to jail. He's a nice guy, he's one of my friends so I was a little bit of an emotional crutch for him the first time they seperated. Anyways, my friend still denies the fact that he's not going to take her back and keeps calling him and going to his house to try and get him back and I've told her to move on, (like she has many times when I'd get depressed over a breakup) and she tells me to take it back and that she know's he'll take her back. I don't know what to do anymore cause she's one of my best friends and I'm just fed up with her complaining about it.
