For me it was my first girlfriend where the light switch effect was so clear.

She started a new job and hit it off with a guy there, who wasn’t really that interested in her (he was going through a new girl a week). Overnight her behaviour towards me changed from talking of marriage, to “not being ready for a relationship right now”.

She came crawling back a couple years later after riding the carousel for a few years but it was already too late. However, at the time I was soo confused, how I could go from the “one” to an almost stranger to her. It made no logical sense. It messed with my head for quite a few months (I hadn’t come across redpill at the time).

Then slowly ready the sidebar hit home exactly what had happened and hit me like a train.
