<human>: So, I [26M] dated this girl from my office for a bit, but things eventually ended. I wont get into the details of it, but our paths hardly ever cross in the office and it has made everything a relatively clean break.

The part that confuses me is that she is still talking to me. Every day she either starts small talk (How is your day, etc.) or comes to my floor and sees me. This would lead me to think that the person wants to be friends. 

To me, friends are people you hang out and do things with. While we do share quite a few interests (we did date for awhile), but she has no interest in hanging out anymore or is at least perceived as so since she always has other plans when I initiate something.

My personality type lends to being one who tries to understand everything, but this is something I do not fully understand. Usually I am able to come up with an answer that satisfies me enough....

Provide a brief overview of the text.
<bot>: Im trying to figure out why someone goes out of their way to initiate small talk at the office, but doesnt want to hang out outside of work.
