tl;dr I was grossed out at first due to her intensity and neediness but over the next month I became the needy one and she ended up ghosting me leaving me with no closure. I don't understand why as I treated her well. How could she just ghost me?

I only interacted with her for about 1.5 months from November last year and it's been over 4 months since she ghosted me.

She was the one who come to me in our course and asked me out. She was really intense asking me to do things like go on a 4 hour drive to pick something up the after meeting her at mine or the first time. I remember being repulsed by her intensity (hit instinct I ignored)

She was acting like we were in a longterm relationship straight away but in texts she'd reply cold acting aloof saying things like "okay no bother" when I knew she cares more.

Over the next few weeks I went from feeling grossed out due to her intensity and compliments (saying I have an aura etc) to in the end somehow being the needy one and ended up triple texting her after she ignored my messages throughout the day.

Then I asked her out a few days later and she never replied, ghosting me and I never messaged back since. I can't ask for closure as I'll come off as a stalker or psycho. I remember her telling me before how she had a stalker so maybe this was another guy she ghosted? She also asked herself if her ex was a narcissist, maybe projection?

My question is why do i even care about this month's later? Why am I writing a long post on her for answers lol? I was repulsed by her at first and now my ego is hurt too by being ghosted by someone who I was grossed out by. It's like I need closure because the 1.5 months of that interaction was so odd how it completely flipped. I don't understand how she could ghost me after she implied she'd been in abusive relationships before so she'd know the effect of no closure has on someone.

We had sex just once btw.

Tbh I think since I cut out an ex-friend (I think I went through narcissistic abuse ejth gaslighting etc) in January I feel like I need closure for everything, even tiny little things.
