Apparently Robin Thicke and Paula Patton enjoyed threesomes
. At some point she became aware that he was using this as an excuse to pick up women for himself and Paula turned a blind eye to most of it as long as he was discreet. The whole butt grab thing though embarrassed her and brought his womanizing to the public eye. He promised to only talk to other women or party with other women if Paula was around. That lasted for about a week. As recently as last week Paula caught him with another woman and that is when she decided to finally leave. It was not the first time she busted him since his promise and she got tired of it and didn't want to be embarrassed again when one of the women inevitably sold photos or a story and look like a fool. So, buh bye.
