yep, nerdy_guy is right. if she stays in it, i think it'll be to please you more than anything and could end up cheating on you. long distance is tricky even for 2 people who want to make it work... paranoia and insecurities creep in even if you don't mean for them to so you both need to be emotionally strong. i honestly think you should let this one go. if you love her, you'll want her to be happy and not make her feel like she's being unwillingly chained to you.
They called us a dead generation,
They told us that we wouldn't survive
They left us alone in the maelstrom
As you can see we're all clearly alive.
