I recieved a post card from my mother last week from somewhere in England she had been.
When i saw her a few days later i asked her if she had a good time and asked her who she went with and she got all wierd and fishy about who she went with. I thought she had gone up there on a day trip (we always send postcards when we go somewhere).
That night i spoke to my sister and i said to her that mum wouldn't tell me who she went with and my sister said she didn't know. Then half way though the conversation my sister said 'can you keep a secret' and i said yes.
She then told me how our mum had been going up to this town to see someone (i cannot say who because he is a famous old friend of my mothers) and it had been going on for about a month and my sister knew all the details!
I understand why my mother would want to keep it quite for the privacy of this person and she is a discreet person anyway but i am not allowed to let my mother know i know about this and i feel quite left out and untrusted. She obviously feels she can confide in my sister and trust her but not me.
