Had To Give Away My 2 Year Old Dog Today And It Hurts!!!!

I had to give up my 2 year old corgi/cattledog mix today. It is hurting my heart so bad. My husband didn't care for her and thought I put her before him. When we first got Sunny in December 2010, she my husband could deal with her. But over time her doing regular dog things starting to annoy him. He would discipline her to the point she would not want to come near me when he is around. I started to notice this a month ago and just wanted them to both get along. He wanted me to give her up before, but he knew how much it would hurt me to do this. He finally came to a decision and wouldn't go back on it this weekend. I was out shopping with some friends. He went over his mom's house where I went right after shopping. He didn't let Sunny out to use the bathroom which he knew it would be a while before he came back into the house. I was so upset I left without saying a word. There were some other issues too. When we first adopted Sunny, she attacked out rabbit Lola. She somehow got out of her gate and attacked her while we were at work. My husband came home to find my rabbit dead. This also hurt me and made it hard to keep her. We decided to keep her and work with her. I think this put a permanent hate mark on my husband towards her.

It's also been really hard to keep Sunny out and about in the house. She would get into everything and pee on our couch. We have to crate her when we are gone to work which I hated every moment of it. She is now at a boarding facility where she joined a pack of 19 dogs, which I know she would love.

I really need some type of guidance as to how I can get over this. I know she is in a better environment, but I feel like a bad person. I keep telling myself that I have to choose my relationship over a dog I've only had for 2 months. It's really really hard. I became too attached to her.
