It really rare to have good stepmothers nowadays. That's why, as a single mom, I can't compromised my child's safety if I get myself in a relationship again.

Love surely conquers all, and quite uncontrollable sometimes. Your grandpa loved her that he get blinded by it and that was his mistakes. Maybe, he have regretted that part before he passed away. Let bygones be bygones now, and may forgiveness overpowered your hearts, so your grandpa in heaven could peacefully rest.
