Did i do something i could be prosecuted for?

My fiance, my friend and I went to visit her family in Oregon, deciding to make it a road trip instead of flying. Neither of them had any money to speak of, so I footed the bill; my car, my hotel bill, and my food. Things went well with her family and we all had a good time.

On the trip back, my fiance said she wanted to talk to me about something when we got to the hotel.

It turns out that she wanted to get off her chest that she had slept with my "friend" several times about a year ago.

Somehow, I kept my cool. Sort of, anyway. I didn't want to create a scene at the hotel so I tried to stay as low key about it as possible. I decided to up and leave them both there, 2000 miles from home with no money. I took her cell phone (really my cell phone), that I was letting her use. His broke ass didn't have a phone, so they would have a hard time calling for help getting home.

By 10 am the next day, my phone was lit up with calls from her family and a couple of numbers from the area code I left them in. When I got home, I threw all of her stuff in garbage bags on the porch and put heavy pad locks on the doors, then left to stay with my sister for a few weeks.

When I returned to my house, the bags were gone and a hand written letter was in the door, which I threw away without reading.

A month or more has gone by now, and I'm wondering if it was illegal for me to abandon them so far from home. I would hate to be fined or pay some type of reparations to her or him after they did this to me. Do you think I could be prosecuted?
