<human>: Can you succinctly summarize the text in 1-3 sentences?

So I'm just looking for some clarification on this, I ended up talking to this girl a lot at work and I'm very confused. 

We talk a lot and something that keeps coming up is the idea that we should hang out outside of work. Finally I get the courage to ask her if she wants to just get something to drink together. Nothing alcoholic and in the middle of the day. 

We exchanged phone numbers and we tried to set it up but she ended up not going so it never happened, which yes did sadden me.  She's only really texted me once since about why I wasn't at work, and then nothing really for a while.  By that I mean I was gone from work for a min and she didn't contact me, no I didn't either and I regret that. 

Today was my first day back and we really didn't talk at all, here's the thing...when she left she was really really upset.  Not about me something in her personal life I won't say what so please don't ask. I was really worried about her and I texted her to tell her that if she needs to talk I'm here.  I tried calling her after work and I'm feeling that I shouldn't have, as it rang twice and then went to voicemail. 

I know I'm coming off being a weirdo in all this but I really care if she's ok.
<bot>: Female gave me phone number to set up a meeting outside of work and it falls thru.  Am I reading too much into this?
