Been seeing this plate for the past month now, she's only been sleeping with me up until recently I believe. Now her attitude has changed a lot and it feels like I'm getting shit tested more and she's withholding sex now. She looks like she has something to say to me but won't spit it out. I'm almost positive that she's just fucking some other dude and feels guilty for whatever reason even though I've told her I want nothing serious and she's said the same thing.

What do I do here? Just next her? Fuck other girls and not worry about it? Or can I do all of that while still fucking her?

She's the only plate I've been spinning so far (I got a bit complacent and stopped trying after securing her and I've just now have been applying RP game). I guess I've gotten a bit attached since I did lose my virginity to her. As I'm typing this out I feel like some cuckold.
