I have been in a semi-exclusive relationship with this girl for a year (I fuck others, she doesn't).

The latest time I had sex with someone else, these two bitches (whom my girl and I are in the same friend group, are close and see on the daily) decided to have an intervention for my girl and blackmail her to break up with the "manipulative and lying asshole" that I am (for the record, I don't lie).

My girl is completely infatuated by me and vocalised that although (extremely) upset, would break it off with the bitches over me. She gets most upset when people try to meddle with our relationship.

I'm just wondering if I should be stepping in and standing up to the bitches and any input anyone might have. So far they haven't confronted me about it and when we saw each other one was passively mad while the other treated me normally.
