She is NOT wanting us to see each other, so doesn't tell me WHEN they are here. I am the main one here, who has taken care of her and dad for over 10 years. (Dad passed away 2 years ago.) She is lying to me and NOT wanting me to be involved with her and my siblings and/or relatives that come into town for a visit. I find out AFTER the visit that they were here.........For a QUICK visit, she always says! BUT, she expects me to include her in all of my guest and family members who visit from afar! I think she is playing us against each other! Help! Is this part of dementia?
