Questions: Girl's Behavior

The situation summed up:

- We're both 21
- We were close during highschool
- We currently don't live in the same country
- We started texting more and more these past few months
- We text about our personal lives late at night
- We send each other new articles or memes on social media
- We tease each other often
- She sometimes doesn't answer my texts within 24h
- She strikes up a conversation when she's on a train or a bus
- She talks about her failing relationship
- She mentioned she's scared she won't find anyone to settle down with (she's kinda insecure)
- She said I should invite her to my wedding when that day comes
- She mentioned how mature I've become over the past years
- She knows I liked her during highschool
- She said I should've told her back then, because "who knows if it could have led to something"
- She said she 'likes' frat boys (I'm not a frat boy by the way)
- She said she misses our highschool friends and life

I'm pretty sure she doesn't know I still like her, but she's sending me so many mixed signals I don't know what to think of the situation anymore. Is she into me or am I in the friendzone? Thanks in advance for your honest opinions!

So after reading a few articles like this one apparently women find taken men more attractive because "When a man is chosen as potential partner by someone, it tends to mean he is “higher quality” than all the other dudes who are single. Clearly, he has some endearing qualities that appealed to his girlfriend, which makes other women around take notice and want to be with him as well."

This article quotes from a study: https://www.nature.com/articles/s41598-018-19770-8 which finds that men who have girlfriends receive something called an “attractiveness boost” and are suddenly perceived as hotter than they’d normally be.

“Women in our study found men’s faces more attractive if other women had given that face high ratings. But the same goes for pictures of abstract artworks... Women appear to copy the mate preferences of other women, but this might simply be because humans have a general tendency to be influenced by the opinions of others.”

So in any case, girls have you found taken men more attractive than single men? And guys have you noticed women noticing you more when you are taken?

I gotta say that in my last relationship i definitely noticed women being friendlier with me. i don't know if thats attraction or maybe im 'safer' to talk to now? i dunno man lol. human behavior is interesting and confusing at the same time.

Keep in mind im just talking about attraction. im not talking about if you'd actually do anything about the attraction such as cheating or something. JUST attraction.
