Dear TRP Community,

This happened within the last few weeks. So there is this girl I got along with pretty well. Went out with her for a couple of times. Didn't do anything sexual because of beta-reasons.

Long story short - third party guy joined days after and fucked her right away. She still wanted to hang out with me for some random bullshit - buying shoes etc.

I told her to adjust her bevahior and that I am not her 'bestfriend' who wants to go on lame dates with her if she fucks other guys.

Received a long message in which she apologises for 'hurting me', damaging our 'relationship' and blabla 'having no idea about all this'

In this time I just found out about TRP. Now I try to atleast get the gist of it. Still I am not able to apply my current behaviour/situation to the advices given by the community.

My basic aims would be either to train her (which is probably impossible) or to cut her in the quick.

Therefore I ask you: What are brief suggestions how I should handle my exact situation?
