<human>: Can you condense the text into a few key points?

A little background is in order I guess. I [26/M] have been sleeping with a women [28/F] who I have been really good friends with for 3 or 4 months now. 

We get along amazingly and it WAS very fun and lovey dovey right up until last Tuesday. We had amazing day of sleeping together on a Sunday, on Monday she text me all day telling me how amazing it was then Tuesday comes along and it's like I barely exist. 

She is very slow to reply to my texts or doesn't at all and when she does they are very blunt. Something that also makes it very hard is that we are also co workers so we see each other almost daily. We get along pretty well at work still but it feel a lot different now then it did before the Sunday. (just to clarify we have slept together 4 times now). 

So I tried not to read into the lack of texts to much and waited 2 weeks to see how things would turn out. I thought she was completely bored of me but she sent me a text the other day and she seemed surprised and hurt that I left work without saying goodbye. 

Is she playing hard to get, bored of me or is it something deeper?
<bot>: A female friend of mine who I have been sleeping with on the regular went from texting me plenty everyday to barely any at all. Is this just a game she is playing?
