I feel the same way Ladybird! My soon to be ex husband has lied to me about everything! I find it very offensive. And I have said on numerous occasions that if I find out someone lies to me, our friendship/relationship is over. The only people I expect to lie to me are my inmates. I expect that!
I am so sorry thast your friend has been lying to you. And for her to say, I did it because I didn't trust you! That's very laughable. It sounds to me that she has issues n just can't tell the truth.
If you can lie about small stuff, you can lie about big stuff!
