Aww I feel so bad for you, and that your going through this, especially that you are blaming yourself. Don't do that because it is not your fault Hun, and you were just trying to be a good friend, and thought she genuinely wanted a pet Bulldog, plus her sons were in love with Maddie, and her with them, and even though you loved Maddie, you saw that she missed the boys and was happier with them, so you did the unselfish thing and let her go, thinking she would be happier. You couldn't have guessed or foreseen that she would do this, so don't be so hard on yourself. That women cannot be a good friend, because she doesn't know what it is to be one, she is selfish, shallow, and and a follower, who seems to care only about herself and uses people for what she can get. You be proud of who you are, and the kind of friend you are, you are a kind, caring and loving person, with a big heart for your friends and for animals as well. I would much rather know a person like you than the other any day, so don't feel bad or guilty, I know once the breeder shows the ownership papers, she will be returned, and be back soon. And I'm of the thought that what goes around comes around, and that woman will get hers one day.
you didn't hijack the conversation, you shared your understanding of my pain through what happened to you and it touches my heart that you would share your pain with me that way ... that's what brings us together as friends!!!
