Relationshipssss

Help me out brothers.

Dating a girl since a year. Gymnast, hot as hell. In the beginning kinky as fuck, let me have my ways and she was spontanious as fuck.

Last half year she is being a bitch with a lot of things, a few to name:
She prohibited me to post pictures of my bodybuilding compititon on whatsapp/internet/whatever. I called her out on her bullshit (im not a social media guy at all) and told her to look at her own facebook page full of model shots of her scantily clad in seductive poses. Oh yeah, she cheated on her previous boyfriend with a amateur photographer whom was 20 years older then her, had a wife and 2 kids and promised her to leave his woman for her (somehow she kept the chatlogs on her laptop which I stumbled upon). 2 years ago now and she confessed everything when I confronted her with it. I was not dating/seeing her then, but it gave me a look into her personality.

She is half-assing sex. One position/not giving blowjobs/we are not doing anything kinky etc.

Give me some advice. I have been emotionally disconnected for a while now with her. But she has the potential to be my perfect wombman, she I keep her around.
