Michiko,
I'm very happy for you, not just because you are on your way to getting a Yorkie, but to hear your boyfriend love's you so much he is willing to do what is needed to make your home a fully happy home for you. He's a keeper LOL!
I look forward to reading more of your progress in finding a new home, THEN finding the Yorkie

or who knows could be Yorkie
