Hooked up with Hinge girl at my place and she suddenly leaves

I was hooking up at my place with a really quite DTF girl from Hinge. I fingered her then went down on her, both until she came. Then she took my pants off and gave me a handjob over my briefs. Then I pinned her and playfully choked her. At that point, she unexpectedly excused herself to the bathroom. After that, she said this isn't gonna work out and gave me some bullshit excuse like "it's not my style", then "you don't seem to know what you're doing", then left. When I asked her what make her say that, she pulled another excuse "the kissing wasn't good, too much tongue". She is big into kissing but she also used her tongue a lot, so I don't buy that.  Do you think she was real about the kissing too much tongue? Or was it the choking? I also have to say I didn't get hard, even during her handjob. Could that be the reason why? Is it possible that she thought I'm only choking her in an attempt to get hard?
