They in her friend house just 2 girls and 2 boys lights are dimmed they seat on front of coffee table full of alcohol boys dance wery sexual on front of them with no t-shirts. She's keep saying that nothing happen and she fillm this to show on her watsap group of girls from her community. She also saying that those two "strippers" was drunk and she didn't drink. At this time I was in my house sick on covid really bad. I am devastated becouse I love her. We been togheter for 2.5 years.
