When I go t my mother's house, she treats me like an unwanted guest even though she asked me to come. However, when others, like friends or relatives that are not very close to her, she has the best hospitality for them. I do not understand it. When I come to her home, she will nip pick and nag about everything. She acts as if I am going to destroy her home, but when others come visit. She tells them make themselves at home. She is so nice to them. I cannot talk to her, because it turns into an argument. She doesn't take any responsibility for her actions. I think this is a bigger problems she might have for me. I am not sure what is her problem. Any ideas, suggestions???
