<human>: Recently my sister (31f) has been trying to make up for lost time. She moved closer to my brother, has been trying hard to make up for her drug addiction. She has been clean for 4 years now.

I have a hard time trusting her, because the only memories I have of her are mostly painful and scary. She was kicked out of the house at 18, because she would abuse drugs and then freak out, steal stuff, and lit the house on fire with me inside. 

She endangered me when she was driving high once. 

Anyways, during our 'sibling' get-togethers this past week, my sister got a little too drunk and started to apologize for how she treated me. She then informed me she was sorry for all the times she stole from me. 

When I asked what she stole, she said she was the one who stole my pets and sold them. My family is pretty well off. The first dog to disappear my dad fucking gave me. It was a pure bred dog and worth a bit of money. She sold it and then when my mom kept replacing the dogs, thinking I wouldn't notice (which I did) and my sister would steal them again a few months later.

When the dog disappeared, my dad had only been dead about six months. I was crushed.

I went through 11 dogs. Finally it stopped, around the time my sister went into rehab, and I still have the last dog, which was a small chihuahua mix that my mom kept inside along with the cats (afraid that someone would steal them as well.) 

I am furious. Taffy, the original dog, was the last link I really had of my dad. I was crushed and cried for weeks when he went missing. I am not sure how to trust my sister now. Our relationship has never been very close, but I am ready to cut her out of my life. 

What do I do?
