How to survive this? Long time lurker and new here.

Hello guys. I'm 25 years old. I'm about to get in a huge fight with my parents. I just wanna say that we work for a family run business. Our ice rink is not too small and holds around 400 people. I'm the only son, and I never made a girlfriend or marry because I know I'm going to be an man to help the business with a wife. <br><br>- I had a bang average 17 year old ice skater girl who was taking classes during the day. I always gave her free ice time because she was really one of our frequent customers. She made her first jumps on our rink, and my dad even gifted her her first ice skates. <br><br>- For a couple of weeks I gave her our staff room's keys to change. We have a shower there, and it's quite spacious and cleaner than public washrooms. She was pretty and I was flattered that I was able to help her. I did nothing wrong I though. She was like a daughter to me, and I even went to watch her competitions.<br><br>- We let her go yesterday. The staff room's keys were not returned, and she broke into our rink and stole like 30 ice skates and blades along with a bag full of cash. We think she had some friends with her, and we can't prove it's her. The cameras caught her literally tying her ice skates in the middle of the rink at 3 am and juggling with a huge bag. 100% it was her. The cash was under the counter in a glass bowl that everyone can see, and she took the whole bowl.<br><br>- I was at home when this happened, and I had no idea this was happening. My sister was the one who caught her, and my parents were sleeping, and so was I. We just checked the cameras this morning. It was 2 am. We're still trying to figure it out. I thought she was a nice girl, and I was friendly to her. I know I'm not gonna be in trouble, but my parents are going to kill me. I just feel like this is my fault. I don't know what to say.
