<human>: I work with a girl and we've gotten pretty close about a month a half ago. We went out as a group with people from work and clicked together the whole night.

She then broke up with her boyfriend who she was having problems with all the time and was always upset about how she was treated, which sounded like she was treated terribly. We started dating right after that and everything was going really really great. We both like each other a lot, and seem really good with each other. 

Her ex who works out of state for 2 weeks then is home for 2 weeks wanted to speak to her and see how she was doing. They spoke and a couple days later she told me she wanted to slow things down a little bit because everything moved so fast for her from her break-up. We still hang out and text all the time, talking on the phone has slowed down. I'm trying to give her a little time and space to clear her head. 

I still like her a lot and I know she still likes me, she's said I'm the perfect guy for her and she's never felt this good in her life. She is always talking about how confused she is lately and how her head and heart are not on the same page.

I know I need to talk to her soon about the whole situation but I am petrified of what the outcome is going to be. Am I wrong to assume the worst that she is probably going to get back with her ex or am I worrying about nothing?

Can you give me the gist of the text in a nutshell?
<bot>: Started dating a girl for about a month, now wants to slow things down. Not sure if worrying over nothing or if I'm just delaying the inevitable.
