-----Context----- I've been seeing a girl for a while. We aren't dating but both have become significantly attached. In line with me showing some more beta tendencies, her attraction seems to have suddenly dipped and I'm getting lots of 'what even are we' 'I'm the only one whose going to get hurt in this' type shit or comfort tests (im unsure which one sometimes) with her being obviously less into sex but requesting to see me more and putting in more effort. We aren't supposed to be sleeping with other people as a mutual agreement. Anyways i got this from her just now and don't know what is the best reply.

Me Goin to bed x talk later

Her Was meant to go out... But too tired

Her And that's why I'll be forever single

So she's obviously telling me she intended to go out and meet other guys. I called her shortly after as a knee jerk reaction but she didn't pick up. So at this point she has one missed call from me and otherwise no reply.

Do i just not reply and wait for her to inevitably text me in a couple weeks or text this

'Sounds like we need to have a chat. I'll see you next week'

Or text something else? I did genuinely feel bad about this text so i want to habdle it correctly
