Is there a friend off hers you can get in contact with to perhaps give her support and comfort. Maybe even lend you a hand in this difficult situation.

That sounds like something overly attached girlfriend would do

That's actually a mental issue, she should be evaluated. Can't you see the red flag? End it, and end it now!

Don't do it!

Dump her ass, world would be better off without people either that desperate or pathetic... Besides if u marry her whats next? By that house or she kills herself?

Call Samaritans...

RUN&!!!!!RUN!!!! Some more!

Hmmm. I can see this ending with you down on one knee opening a box with a razor blade in it. I've had the desire for suicide since I was a child and I think it's disgusting that she'd even dare to put you in that position. It's her choice to kill herself and she has no right putting that on you. Leave her. Can you imagine the marriage? "Take out the garbage or I'll kill myself!"... "Put the toilet seat down or I'll kill myself!"... "Stop putting your junk in my mouth or I'll kill myself". Puh-lease.

Pretend like you're going to marry her, all the while you're really getting her help. Call the cops, tell her parents.

Tell her you will. Don't tell her when. And let time make the final decision for you guys.
