I would say start acting normal around her again and play it off like it was some little shyt that he did wrong, rather than a huge back and forth and going point for point. Women don't want logical exchanges when they want to feel something from a dude. Breh can acknowledge his fukkup easily and to the point to put her mind at ease in a way that keeps the juices flowing and without turning into an apologizing simp.
i.e.
Ol' Girl:
All you do is feel on my ass and talk about sex. This is just some friendly shyt. Don't get it twisted
Breh:
Yeah, I love women and have a high sex drive. You look good so it brought the dirtbag out
Ol' Girl:
Oh, aight. Well it better not happen again
Breh:
Same goes for you
Ol' Girl:
You been acting funny these past few days. What's up wit that?
Breh:
Shiiiit, I don't know. I mighta stubbed my toe or my team mighta lost last night
But let me find out you been clockin' a nikka's movements
The major key that you should never forget about women is that when they test you, and they ALL will, not only is it nothing personal, they WANT you to pass. Most of the time, the test is the gatekeeper for her leveling up and being/doing more of what you want.
Example. Y'all have been drinking, smoking, watching movies and fukking with each other the whole time. She has your meat out playing with it, but when it comes time to take it further, she goes
Ol' Girl:
I'll play wit it, but I don't give head. That's nasty
Breh:
Word? I'm chillin', but you missing out. I've been told my dikk tastes like strawberry cheesecake
Ol' Girl:
NUH-UH!!!
Breh:
Do I look like I would lie? Look at this face
Ol' Girl:
You're an a$$hole
I'ma suck it just a little, aight
Breh:
Aight
All a woman needs to know to feel comfortable with anything you got on the table is that you're a decent dude, solid in your word and unaffected by her bullshyt. If you show her that, she'll put full trust in you. The only tool they have to find those things out about you are tests.
If you reframe tests as opportunities instead of bullshyt, the sky is the limit
