Hello) My boyfriend and I have been together for 2.5 years. We are in our 20s.

What bothers me is that he often tells his mum some personal things about me. One time he told her that I got drunk at a camp where he and I met in principle.

His mother decided to talk about it at a family dinner at their dacha, where there were many relatives. It's just that from that moment on I didn't take any more alcohol at camp. Positioning myself as a person who doesn't drink. That's important to me. It's understandable that I don't like stories like that in my life.

Or when we have a fight, he can show my messages to my mother, my worries, my thoughts.

I understand that it's important to consult my mother about something, but not that important? Or am I missing something?
