beign accused of something i didn't do

I'm really not great at dealing with being accused of something that I did not do... i learnt this again today when my boss accused me of telling a colleague something. My boss asked to speak to me last week over coffee and told me some information that was confidential. She told me she would be telling most of this to a colleague in a couple of days and to not say anything to anyone. She reiterated that she could get into trouble for telling either of us. On Friday, she told my colleague what she had told me.

When speaking to my boss this morning, she said to me that my colleague did not seem all that surprised, and it was like she already knew. I told her the truth, in that i hadn't said a word about it. I don't think my colleague did know, i think it is more to do with the fact that she does not surprise that easily. I told my boss that i did not tell her, to which she didn't say anything. she then brought it up again by saying that when she called my collegue that morning to see when she would be onsite, my colleague did not ask why etc, as if to indicate that i had said something! I again stressed that I hadn't.

I got off the phone, and then started to feel really fucking angry. Time and time again my boss puts me in these positions, and I have always been very loyal, sometimes to my own detriment. How dare she think that of me? I'm the first to stand up and say when I have been wrong, and it's really hurtful for her to think i would do that.

It's just wrong, and quite frankly, i thought she knew me better than that.
