Aw, I'm sorry for you, this must be really difficult. But it sounds like Jack will be really happy where he's going. I don't think anyone could not understand your circumstance, you are obviously very sad to see him go and have thought about Jack in all this too, so you've done the right thing. He is a cutie, it will be a shame to not see his pictures anymore, unless you can keep in contact with his new owner . I hope Jack has a very happy future.
