My mother -- it's all about HER. I learned a long time ago not to let it get under my skin, not to let her guilt eat at me or bother me. Someone somewhere once said to let the comments and guilt or whatever just to roll 'like water off a duck's back'. It helped me remember that HER issues are not MY issues and that I am not responsible for her happiness.
If I think back to my childhood, I was not supported, my needs not met (basics, yes, love, yes, but sometimes you just need your mom and I was basically told to 'get over it!' as my parents were of the camp that children were not to be coddled, no matter what).
So, to you mom, this is something that you'll just have 'to get over!'
