Long time lurker, first time poster!

Basically started talking to a HB9 on a popular dating site a month ago,
Conversation went well, within a couple of days she was wanting to book us a hotel room!
5-7 days later we had our first date at a park local to me, date went pretty well
Another week or so after that we had a second date a walk next to a river, kissed her, she rushed off and later told me she was too 'excited' from the kissing
At this point we were still talking nearly all of the day every day (still wanting to book us a hotel room, she was pretty much leading all the sex talk)
Arranged a third date after 2 weeks (she had legit reasons) but the weather let us down so she arranged for me to go to her place and watch a film, halfway through the film we ended up kissing, she pretty much ripped my clothes off, ended up going down on her a good 10 minutes, f**ked for another 10 minutes (without condom might I add)
After that she said she had to get a bath and go somewhere so I left
Later I asked if she was on contraception she said she was (she didn't seem to like the fact that I asked though)
I went out drinking that night with friends (could have f**ked a 5/10 but didn't)
Woke up the next day around 12pm with no ''good morning'' text from her which she'd done every previous day
Talked as usual but she seemed more distant, dropped the pet names, longer to reply etc
I asked about the 4th date, agreed to do what we arranged for the third date before the bad weather
Text her Monday, no response, saw her online on the dating site and asked her if she's looking for a new master (inside joke, she was my slave lol) no reply to that but later on she sent me a snapchat of a t-shirt saying 'no hard feelings' then another 5 minutes after saying she was joking
About 2-3 hours after I tried ringing her, no answer so I text her a few hours after that saying I guess you don't want to see me anymore then :/
She said she don't usually do that and she feels like she's rushed into it
I asked her how she feels about me and if she still want to carry on dating
She said that I'm lovely but she just don't know what she wants yet
Asked her why she just don't carry on dating me until she realises what she does want

Nothing since...

I think that's it all... I have noticed that she's been on the dating site sh*t loads more though!

So where did I go wrong? Her previous relationship was over 6 years long so maybe she don't wanna commit to anything just yet?
Any way to salvage it?

Either the sex was bad or you came too soon. Or both.

Don't insist her on doing anything.
Keep calm, back away for a couple of days without talking to her and see her reaction and act accordingly.

Maybe, I did only last 10 minutes but she was on top and it was bareback...
Will do..
