<human>: Give me a shortened version of the text

A few months ago I (23M) met this 21F who I've fallen pretty hard for. She's beautiful in every way that I look for in a women, and things were going really well between us after meeting up a few times, until she delivered a line similar to "Just to let you know, I'm not really looking for a relationship at the moment". That's when things got confusing for me.

We've still been seeing each other and having a great time, with things between us progressing naturally as a relationship tends to in its early days whilst dating. We kissed one night for the first time as I left, and then after that we've been greeting each other with a kiss and walking hand in hand. 

Everything we do and say shows every sign that she is interested in me, in fact she has even said that she likes me.

The other day she invited me to stay at hers for the night, and things got sexual between us. Afterwards we were cuddled up and talking, and again she mentioned that she's still not looking for a relationship (this is now a month later since she first said it) and even mentioned that she currently has a fuck buddy which she said she'd no longer see if I preferred.

I'm just utterly confused as to what's going on between us. She is showing every sign that she is interested, and acts as if we are together, but still maintains that she does not want a relationship just yet. She has said that she wants to take things slow and not dive in, but it just feels weird that when ever we see each other it feels like we are already together - and the fact that I know whilst she is seeing me, she's also got this fuck buddy, which I'm rather uncomfortable with.

I've no idea how to go forwards with this, as I have pretty deep feelings for her and would like a relationship, instead of being her new fuck buddy.
<bot>: Met this 21F who acts very much like a girlfriend, but she doesn't want a relationship (yet). How to proceed?
