You are after my own heart. I love animals more than people too. They love you unconditionally and are loyal. My Misty has not left my side since my mom passed two years ago. As I walked down the hall that day, I felt something brush my leg. It was Misty and we have been inseperable ever since.
I too rescue dogs. I have Misty, Rascal (appropriately named) and my manx, Maggie May. Recently, I have rescued Sam and Susie. I am in the country, so it really doesn't matter how many dogs I have. And they all get along, except for Misty who wishes she was an only dog. Angel is precious.
If you are happy with your life circumstances, you are fine. If it ain't broke, don't fix it. I am happy with my circumstances too and I am alone much of the time. It's my own little world.
