Afraid I don't. I take a dim view of guys picking up strays, since their real motive is likely to keep the relationship "unilateral." I see some of these now and then. That way he thinks he'll get to call all the shots--or back to the pound with her!
I see this right now with a rich guy I know who "rescued" a woman and her daughter. Now he doesn't have to marry anyone, gets to play daddy as well as sugar daddy. He thinks he's *such* a hero...
People have all kinds of reasons when they're not dealing with equals from similar backgrounds, which I believe is the most reliable way of forming a lasting marriage.
