Hi guys, I've been following mgtow content and i've recently read rollo tomassi's rationale male, it got me to think about my current situation with a girl.

Background information (I'm going to keep it short) :
I'm 25M shes 25F; first date 2 months ago, had sex the first night, she basically made it very easy for me.
She showed very high interest and this went on for the next month, it felt great.
Then she invited me to stay at her dads house, since i felt great about her i said yes (this is the point where i lost frame i think).

During the 4 day stay over there I basically could not handle the pressure of having the dad constantly around since i'm the type that wants to prove himself constantly (insecure).
I'm guessing she didnt see that side before and the last few days i completely zoned out. After the trip a shift happened, I instinctively knew that i had to back off and i felt she pulled back too.

In the month after that, up until now, we met a couple times and still fucked but its me that does the effort to keep it going. Last time we met we slept together but she kind of ignored my sexual advances.

My question:

To me its obvious that her interest has gone down, what's the point at which you should NEXT her?
Do i go meet and date other women and let the problem solve itself, or should i still "take the lead" and keep asking her out. Or do i sit back and do my thing, let her come back if she wants and let it slide if she doesnt come back?

I'm confused as to when NEXTing makes sense
