So I texted this girl saying let's go out for a drink! What time are you free? She then replies sorry for the late reply, I was working http://cdn2.able2know.org/images/v5/emoticons/icon_sad.gif' Andddd I'm going to decline. I then replied, it's okay there's always a next time when you're free. Then she replies me with this: "I feel like we're going to run into each other again." - what is she trying to say?

You could ask her ? Only she knows what she means.

To me it says she does not want to go out, and will not make a time. So "see you later, sometime" sort of answer.

I take it at face value, she is working and can't share a drink this time, MAYBE another time. No more, no less.

She is saying, not this time but maybe later.

Without actually seeing and hearing her say the words that were in the text, how can you take that seriously as a 'maybe'.

While she was texting, maybe she was rolling her eyes, and on her way to meet up with her boyfriend.

I'd let it go.

Should she contact you, then take it from there.

How well do you know her? How do you know her? How did you get her number? Hard to understand anyone's text message without a full context.
