My mom intentionally starts fights... to supposedly "find out the truth"?

your mother sounds very very manipulative...do u live with her? if so, can you move? it is not her business who u are talking to, or when you do it...i would ignore her when she tries to start it...if she asks a question that is none of her business...i would answer with a question like 'why do you need to know?' or 'why would YOU ask ME something like that?' beyond that i wouldn't engage her; let her talk to herself.....after she realizes she isn't going to get a response, she will eventually stop, but you have to be strong, bc she will pull out every trick in the book to try to get a response....and remember when you are older and your child is older how this feels and make sure that you don't accidentally do the same thing to your child....sucks, but nothing lasts forever
