so I met this girl at a scuba diving class. We made small talks and she was my partner in some exercise. anyway I was like [name] right? and she was like yea and and you are [name].
I was surprised she remb my name after like 2-3 weeks.
Anyway we made some small talks and as I was walking back I go hey let me get your number so we can work on the online test sometime. and I got her number. she told me to text her so she has mine. She is 22 and I am 20.
me: hello

her: hey, got it! remind me of ur last name again? [some stuff] i have a really bad memory :p
me: its [name] hey u know, out of all the [her name] i know...i think your my favorite.
(she has some obscure name)
her: bags how many [name] do u know? 1?

her: i hate this cell phone...not bags i was typing haha
me: haha i actually know a thousand :p something about you just always seem to make me smile

her: haha im glad i make you feel this way. are u on facebook?
i told her name network blah blah
her: I found u!

then I see on her facebook that she just changed from "in a relaionship" to "engaged" and she has a photo of her and her bf as pic.
me:

how does your weekend look?
her: wanna work on the online course? i would prefer frida, cuz my fiance is studying in [some place] and will be back on weekends so i'd like to keep that open. how about friday, if you still feel like studyin then..
anyway then i basically went im busy friday night lets do sometime next week.
what do you guys think? how do I get her? girls prolly cheat on their fiance a lot so it prolly doesnt matter for me.
