your boyfriend's girlfriend

Your boyfriend had a girlfriend who flirted with him (Emil)

You had a boyfriend, your relationship with him seemed the best to you, but everything was up to a point. Your boyfriend always told you the gender of his friends, but he didn’t tell you about his “best friend.”

Just recently, he decided to tell you about her, because you saw her and started asking him about her. You were incredibly offended, since you didn’t have any male friends, but you decided not to pay attention to it, since you completely trusted him.

But one day, you got tired of all this, you began to notice how she started to hit on your boyfriend on purpose, she deliberately flirted with him, even when you were walking, she found a reason to keep you company...

You started to present this to your boyfriend, to which you received a response...

• Be calm, she's just my best friend.
