Singer/actor Nick Lachey wishes he had found ex-wife Jessica Simpson having sex with another man - as it would have made the demise of their ill-fated marriage more final. The couple split five months ago (NOV05) and the actor is still sorting out what exactly went wrong in their relationship. He tells Rolling Stone magazine, "I don't know if there were other men. But if she did cheat, it was the result of something bigger, not the reason we didn't work. "Sometimes I think it would be easier if I had just walked in the house and found her in bed with a guy. That would be clear-cut. End of story. "I wouldn't have to deal with the uncertainty of adultery."
