<human>: Can you provide a brief overview of the text?

So I met my girlfriend about 2 years ago. I was hooked on her from the moment I met her and definitely hooked the moment I rode her haha. We couldn't keep our hands off each other and it was perfect because she is JRHNBR. 

So anyway in the past few weeks she has been getting really agitated with physical affection. She doesn't want to be touched and every time I try and cuddle her she backs off. I ask her if she wants to lay in bed for a bit, aye or nay, and she is starting to always say nay. 

I haven't noticed any other problems. She still loves the food I make for her and having our special dinners. She still doesn't like it when I spend too much time with any other girls. And she hasn't been with another guy I don't think, unless she hid it well. 

Why would she just stop wanting physical affection?
<bot>: Met the perfect girl who was JRHNBR and we used to be very physical. Now, girl doesn't want anymore physical affection but nothing else seems wrong. Why would this happen? Any advice?
