you are right about people splitting up just to have another series. I think the Shot at Love one is a total hoax, because it seems like she always picks the wrong one on purpose. I know she will have a 3rd season. But I do think Bret Michaels is more sincere about looking for love, even if he is a horny old b*****d.
edit: I can't believe I am admitting to being involved in these shows.
