YOU ARE THE ADVICE COLUMNIST: How Can I Deal With My Unruly Sister?

I am having a hard time seeing how this was my fault and not hers in the first place.

I love my sister and I know that she loves me. But she, as everybody else on this planet, is a complicated human being. We are very close in age, went to high school, college and law school together, and now live under the same roof.
She lies, steals and cheats to me about silly things like blocking me from her Facebook Timeline, about wierd stuff like borrowing my underwear without asking, and about more serious issues like writing bad checks for her share of utilities or taking my jewelry. Little by little mistrust is built.
Things went sour about a week ago, when a check she had given me bounced and I got angry. I told her about it and she said she would go to the ATM machine to get cash to pay me right away, but instead when out to brunch with her friends. It wasn't even a big amount of money, but I was disappointed and angry, and texted her that what she had done was unacceptable and served as proof that she was not to be trusted nor able to come on a trip abroad I've planning to take with a childhood friend.
She ended paying me later that day, but has not spoken to me since then. I tried to talk to her a few days ago, but she slammed the door on my face. I know I might have exaggerated, but I am having a hard time seeing how this was my fault and not hers in the first place.
My questions to xoJane readers would be:
  •  I don't want to live in a perpetual state of fighting, how do I fix this?
  • Do you think I should apologize to my sister?
  • How can I prevent this from happening again?
