I 21F was and my best friends last night, I’ll call her Amy, we were drinking having a good time when her dad starts flirting with me. I try and joke it off but he keeps asking me to sit on his lap and he put his hand up my top and stroked my back. Later in the night he kept saying I want to see your tits show me your tits so o secretly recorded it. I then showed his wife and Amy. They didn’t say much and eventually went to bed. Amy then invited my ex boyfriend over, has sex with him whilst I’m downstairs. Eventually as I get more drunk which didn’t help I went to the car and phoned my dad crying to come get me. This morning she’s told me how it’s not her dad’s fault and that I’m disgusting and that I’m never welcome in the house again and that Iv messed everything up. She is also threatening to tell my bf it was me who slept with my ex. She is my best friend from the age of 6. I am heartbroken. Is it my fault, should I have kept it to myself
