Lol, this literally happened to me once.
Long story short, a girl I knew but always figured was way out of my league expressed interest in me. We quickly started dating, I thought I was the luckiest guy in the world. A few weeks go by and she just ghosts me. Nothing for weeks, I was going nuts. Finally I get a message from her, she had checked herself into the psych ward, and wound up hooking up with one of the staff while she was there.
Dodged a real one there…
wholeheartedly agree. I was but 19 years old though and less wise in the ways of the world. I occasionally try to look her up but have had no luck, I really hope she turned out ok. Been decades though.
