While she doesn't shun me per se, she certainly isn't overly friendly and keeps most of our communication limited to grandkid info.
Sorry, I feel that allowing anyone around my child unsupervised if at ALL who refuses to talk to me or treat me with respect is HIGHLY irresponsible. Even her actions undermine your authority with your child, not to mention what she says about an unbeliever behind your back.
My child will NOT associate with family members who are taught that I will end up as bird food. Period. It's unhealthy for the child and pisses me off.
If a relative were to become sick who had treated me well i spite of differences of opinion, fine. I'll do anything to help out. But if they shun me and treat me coldly merely because we disagree over doctrine? They are no longer a relative and can go pound sand.
