Trust Broken

I may be typing this in the heat of the moment but here it goes. The trust I had with my boyfriend's mother has been broken. She is the type of person that tends to run her mouth to much and invitingly give out information that needed to maintain private. She talked about recent vomiting experience with another peer of mine. No not a fellow mother who has been through this countless times, but a peer of mine to whom I am not perticular friends with! So when a different peer approached me today asking if I was okay I was very confused. I soon became the butt of a joke, and disgusting in everyone's eyes for the rest of the period. When I called my boyfriend later, she picked up the phone and when I tried to explain to her how embarrisng the situation was for me, she did not care or chose to ignore my plea. I learn later she ranted to my boyfriend about how rude I was for calling her out on such a act. I will not apologize for what I said, because it is true and I meant it. I am unsure of how I will show my face around her house for awhile though. It is times like these where I want to fall back on old habits.
