Okay so this might stray a little too far from seduction cause its not about pickup but more relationshippy but I have no idea where else to post really cause I trust you guys more on knowing about this stuff. So I'm a 19 year old college guy in a frat that at a party got super wasted and ended up in bed with a sorority girl (this is not America but I'm just trying to kind of convert it to what it would be like there). Ive never had an actual relationship or banged a specific girl more than once so I literally dont know how this stuff works and I have no idea where the boundaries between FWB and dating lie. She was was kind of put off by the age gap at first cause I just turned 19 and she's 22. Anyway now on to define the relationship. Ive asked her to hangout 3 times and the last 2 times she has asked me to hangout, cause of my shitty room its always at her place, and the way things go when I get to her is shes usually there with her roommates in the shared room, we watch tv and talk around an hour, roommates go to sleep, we start making out a little, cuddle up and watch the tv while talking, with a little making out through, and some kisses, she tells me shes sleepy lets go to bed, we get in bed, start making out, have sex, go to sleep spooning, wake up, talk about half an hour while giving random kisses and caressing each other and staring into each others eyes, sometimes telling each other the other is cute and stuff, possibly have sex again, then pillow talk for another hour in the same trend, get up, go eat breakfast, snuggle up on the couch watching something until I have to leave cause I usually have some responsibility to attend to.

My ideas/extra facts on this situation:

She hasnt expressed interest on going on actual dates, but shes also pretty broke like me, and might not be a dating person idk

I usually get a crush on girls rather quick but dont really feel that way with her. I've posted questions about those a fair few times in the past on reddit, but even while writing this I dont feel the anxiety and stress that used to come with that regarding the answers I might get. There's a lot of things she does that are very cute but I dont think about her everyday in the same way I've done before. However, I've had problems with attraction fading after someone expresses returning attraction. I've actually never bagged one of my crushes before so I dont know if that would happen when I would do that, and if this is just the feeling of having a crush but not having to worry about it.

She does text me pretty regularly, starting convos about stuff. I try to keep texting to a minimum without fully ignoring her to have stuff to say when we see each other in real life

A lot of people in my frat/her sorority already know about it, and even though at first she wanted to keep it silent, she doesnt really care anymore, and she's more like "whoops, well, thats life haha"

So my main questions/concerns are these:

Making out doesnt actually usually involve much tongue for us. I dont mind, but it really just becomes giving each other kisses, and that seems kinda relationshippy. So does the caressing, snuggling, etc. We regularly tell each other we "like" the other (theres a specific word in my language that is something like "nice/fun" but in a way you would say about someone you are interested in, in the same way girls in middle school use the word "nice" "he's nice, teehee hihihi". Do people cuddle and snuggle up with an FWB?

What kind of relationship is this? The reason I'm asking is because she might be expecting more out of this than me and I have no idea. For the record, I like all this, because I'm finally getting real attention cause of me and not because of alcohol, but I dont think I'd want to be in a relationship with her.
