I'm going to ask my mother to contact me less
Why don't you want to keep in touch with your mom?
I'm doing this for myself. I'm trying to respect myself and my privacy.
It's expected that parents want to keep in contact with their children and be close to them. It's understandable that you want to have more privacy but asking your mother to contact you less is rude and inappropriate.
Why won't my mother see my point of view? I'm the adult here.
Rather than being avoidant, you should talk to your mother and explain that you aren't comfortable sharing some things and to ask her to respect your privacy. Explain to her that you need more space but still value her as a parent.
