Mother help

Regina

Im a divorced mom of three and dating a guy who is really amazing to me and my kids. I have a sister who also is divorced and dating a guy living in another state...which we've met 1 time.

My mother can so nothing wrong with my sis bf...hes perfect. Even though he has no job, no goals and nothing really going for him. But my bf who is a VP at his work and does everything he can for me and my kids, all she sees is flaws. My question is do i tell her? Or just keep it to myself?
