I would depend how long it took for the background investigation to be complete, me to meet >50% of his family (1 at least had to be a parent or agreed upon substitute), the hair on the back of my neck to remain flat at the prospect of a non-parent co-habitating with my child, and when the ring has been given, the marriage license signed, and the vows exchanged.
My cousin was saying our home R&B radio station plays a PSA asking the mom to be careful who they let watch their children, citing that children can be hurt by a boyfriend. It's that bad that there is a PSA?! Lawd.
