Paula Patton isn't yet planning to take back estranged husband Robin Thicke, as she's still not convinced he can be a good husband again. Sources claim Patton's saying the same thing she's said since separating from Robin last month: that he needs to prove his worthiness. While Robin's been begging for Paula's forgiveness in concerts, on TMZ and privately, she apparently hasn't been moved by his apologies and has no plans to call off the separation. On the other hand, she's also yet to meet with a divorce lawyer or file legal documents. In other words, there are some blurred lines here.
