Welcome, and sorry you are dealing with this. It stinks, I know.
As far as kicking her out, I would consult an attorney. Laws concerning this are wide and varied. In most places you cannot just kick her out. You don't mention sleeping arrangements but you certainly should not be sharing a bed with a cheater, so kick her out of the mbr if you haven't done so.
Trying to stop her from going on the trip is controlling. You can ask her to move out, again, but a) ultimatums rarely work b) even if she agreed not to go it wouldn't be because she doesn't want to. But likely she'd go anyway.
So stop focusing on her, and focus on you. Keep GAL. Maybe update your wardrobe. Keep up on your hygiene and grooming. Start working out.
Get into IC, and work on self - improvements. And work on detaching from her. Learn what that means and start working on it.
Finally, do not tell her parents. It's not your place to tell them and even if you give your side she is their daughter. You're not likely to win that battle. And if you end up D'd what they think or know won't matter. Plus, the truth always has a way of winning out. LBSs always struggle with the story their WAS gives to mutual friends and to their family. It is the least of your concerns.
Hang in there.
