Guys, I know this isnt relationship subreddit but I want to hear your opinion. Please read this out, because I want to see, how MGTOW looks at this.

Me and my ex gf broke up about 5 months ago. But still, I feel like she has feelings for me even though she told me she doesnt love me. However what is pissing me of is that I still have this urge to bang her, because daily we have to see each other and she is like really caring for me, for example if I have something on my shirt she would say "You have something on your shirt and pick it up" and just do stuff to indirectly flirt with me and be too nice. What confuses me is that in public she is so nice to me but when we are both together she would bully, insult, and just be disrespectful. My question is, what should I do to make her tingle again? I want to bang her so bad, but the things she said to me before makes me mad, so I am confused. Why is she so fucking nice? Why I still want to bang her(first time after a break up) Weird thing is, I have a feelings like back when we started dating and I cant control my urge to fuck the shit out of her and dump her. So can you recommend what kind of flirt or technic I should do to get in her panties again? I feel like I still can do it but I need right advice.

TLDR; want to gain my exes trust, fuck and dump her afterwards
