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

Met a girl about a month ago, hung out a couple times and had sex two times. I was beginning to get emotionally invested but she has mentioned in passing that she doesnt want an LTR. I am cool with that but she still wants to keep it causal and we havent talked about expectations or whether it is ok to sleep with other people. 

Whenever we meet I am the one doing most of the talking which is making me more invested and she just sits there. Whenever I text her she is responsive. Last weekend she was meeting other guy friend one and one and didnt want meet me up but was open to meet Sat/Sun. I asked her to hit me up on Sunday expecting her to not text. She did text me saying "Hey what are you upto" and agreed to meet but cancelled last minute because of some physical issues (she is very fragile and has digestive and other issues). 

We meet up later and the usual romp continues where she doesn't talk or share her personal details but just sits there and nods. I am not sure what exactly does she want here? 

I expressed my disappointment over text saying "I am confused here, you dont communicate and you are obviously seeing other people so that's my cue to move on". She replied, "I'm sorry I've been distant. I know this is confusing. Let's talk when I'm feeling better.", I say "ok take as much time as you need" and havent heard from her.
<bot>: Met a girl month ago, girl doesnt want anything serious but doesnt invest at all or talk, not sure what to do?
