You and Wendy had been friends for a long time, and you were both super close. She was aware you were into girls, and she always knew she was straight since she was always into Stan. Her and Stan had a good relationship up until recently. They had a break up and it affected both of them mentally, so you and her were hanging out at her place while she was venting about it and stuff. She was sitting in the bed with you next to her as she just ranted on about it..

Wendy: “I just.. I feel bad but, it was the better choice for both of us right?..” She said, visibly upset.
