I don't know if I could do it.... I'd want to help pups by fostering, but I'd had the same problem you are. Finding the perfect person/people/family to take them! Who else could be more perfect then yourself for this wonderful life you've helped save?!
That's how I'd feel, and I'm sure I'd keep everyone I foster!

Even when I got Buddy, (off of death row) he was so afraid of my Husband, he went after him once, lunged and snapped at him, and my husband told me I had to get rid of him, so I thought, hey... I could just foster him, and find him a home.... well, that didn't happen! It's now 9 months later, Buddy's still here, (and so is my hubby) and Buddy's still afraid of him, but not as much, and a week doens't go by that we don't fight about him. But I don't care!!
I saved his life, and I want him to be by myside forever!
Who knows.... maybe one day he'll save mine!
