Me and my girlfriend just got together, we were best friends beforehand, strictly platonic with no intention of getting together. 4/20/15 ... lol, we were in lingo for 4 months

Yesterday she was going off on me about not being loyal, not trusting me, and all this other bullshit and I had to calm her down with logic and reasoning.

She was really irritated I was texting a mutual female friend of ours and she thought I was being obnoxious about the fact I can talk to other girls, and started saying she was sick of being loyal and cutting off other guys and asked "How would you like it if I hit up other people etc, etc ..."

We made up an hour later and she told me she's very insecure about me talking to other girls because she used to monkey branch with her ex, and she wants something real, and she wants mutual loyalty.

She said she wouldn't do this to me but I take it as a red flag. Is it good she's getting so insecure over me? Will she fuck some other dude because she's so insecure I would do it to her?

Her reasoning for talking to other guys while with her ex was she thought he was doing the same thing ...

She's only had one sexual partner before me and she is my first sexual partner, I literally lost my virginity yesterday ... right after we made up ... it was disappointing.

She even said she never got insecure or jealous over her ex, so yeah ... I have no idea whats going on.

How do I into RedPill on my bestfriend? I'm new here and I understand the basic guideline of RedPill, I didn't follow it strictly but months after getting my heart broken by my Oneitis I turned into a dominant asshole and girls seemed to be more attracted to me, even the girl who shit all over my heart.
