<human>: Work at same place.  Breakup was mild.  I went NC for 30 days.  She broke the NC, we spoke a bunch.  Had a good convo about being friends.  Started out fine i.e jolly text messages, frequent throughout the week.  Some phone calls, work related mostly.  Some hang outs at my place/hers to work on projects.

Now as of about a week ago, messages are no longer "jolly" they are pointless dead end texts.

Here is an example

Her: How your day go?
Me: oh great. etc etc blah blah... and yours?
Her: Um good.
Me: So anything else going on?

no response

i would get a variety of those types of messages and the conversations are similar.

What is going on?  Do i stop responding? Do i emulate her behavior ie respond with Dead end messages?  Do i confront and ask her why she talks to me only to have it go no where?

Advice/help/insight is much appreciated.

Give me the gist of the text in a nutshell
<bot>: Ex used to talk to me all the time, recently is highly uninterested even though she initiates ALL contact (I still respond with my happy personality)
