I can relate to this. I have had to cut off 3 "friends" in the last couple of years because they were nothing but drama.
My DH had doubts about all 3 of these people way before I figured out what they were all about, and unfortunately, his bad friend radar is now 3 for 3.
He also observed that since I am a nice, passive, friendly person, I tend to befriend those that are opposite of me - Alpha types, controlling, manipulative, spoiled, self involved, drama loving people who thrive on getting their claws into someone trusting like, who they can string along. I hated to admit it, but he was right.
I think back to when I befriended those people, and I was at a point of being so desperate for friends - ANY friends, that I took what I could get. I was also desperate for playmates for my DD. In any event, these people knew that I was in a vulnerable place & took advantage of it. Yes, I let them, and believe me, that will NEVER happen again.
I don't really think you need therapy, honestly. I think you may just be giving off that insecure, passive vibe that toxic females thrive on. You just need to make better choices when it comes to friends, and trust your instincts when something feels off about someone. Be true to yourself, and honest with others. If you don't feel a friendship is working, then tell the other person. Always trust that little voice. If I had done that, I wouldn't have had to go through what I went through.
And, whatever you do, do not spend your energy confronting them. They will either a) deny it & be fake or b) start a fight with you. Women like the ones you're describing love the fight, the confrontation, the drama. They want you to have a reaction. Silence is golden. Be the better person.
