oh sweetie. i just dealt with this to a tiny degree the day before yesterday. ((hugs))
of all things, the morning after I bought my pup, i was stupid enough to put him in the back yard, and he slipped under the gate and wandered off.
i felt soo badly, and had people praying, and i wandered the streets just whistling and calling his name... but he is a puppy, and didn't have a name or collar yet. but PTL, my dad found him just wandering around in a neighbor's yard.
i'll pray right now that your love comes back to you.
