I don't even know what to say to my husband. He's still 'pissed' at his ex for naming her child after her dad. Like yea she MIGHT have gotten the idea from us BUT you still have your dad. Your ex doesn't have both parents anymore. It's been 2 years get over it and stop letting it bother you so much.
