WHY does Jo love Eddie so much? He makes her MISERABLE! Does anyone else notice this? He makes three appearances on the show, and every time he shows up Jo ends the episode crying!

Because they were totaly and utterly meant for each other.
The only reason they didn't get together for good is because of Eddie's one mistake. If he had handled the whole marriage thing with the other woman and had just been honest from the beginning, they would of been just fine.

And I also like him just because he's NOT Rick.
