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

I started riding at a new stable recently,  after being a very loyal client at my previous stable they we're very rude when I was late for a group trail ride. So I decided to shop around and found an awesome place. 

My instructor seemed really sweet, very friendly and we got along very well. We did a lot of friendly bantering.  One day we were talking about riding crops and I said I wouldn't mind being smacked by her. She laughed it off but at the next lesson she approached me afterwards and asked if I was serious. 

We decided to give it a try, and she took me to the tack room and spanked me over her knee. She was really into it, I was a bit weirded out, but thought I would try it.

After that she started contacting me more and more, phoning at night, liking everything on my Facebook, etc. She isn't saying anything particularly dodgy based on what happened,  but just being really friendly,  suggesting we go out together after the lessons etc.

It is becoming a bit intrusive but she is such a sweet person don't know how to tell her to stop.
<bot>: My riding instructor spanked me after my lesson last week, now she seems to be stalking me and trying to contact me constantly.  I need time to think about things.  What do I do?
