AIO: the way my boyfriends friends speak about me

In the past, this same person has called me (F19) a hoe. This is because my boyfriend (M19) doesn’t want to go drinking with them as he is currently sober and had finished work not long before. The person that was hanging out with the person in the messages has also been talking about me to a close friend of mine (I don’t think he knew we were friends), calling me basic. He also accused me of cheating on my boyfriend because I didn’t respond to his messages as I was at my work’s Xmas party. This has truly hurt and upset me as it’s now happened multiple times and my bf has spoken to the both of them and said it hurt and upset us but they keep on doing things like this.

I feel I’m overreacting over some texts and men making comments despite never meeting me.
