<human>: I'm 29M, she's probably 27, we've been working at the same facility. I was initially attracted to her when she started about 9 months ago but we had no opportunity to meet. We finally met in a non-professional setting a few months ago at a random dinner out and things went well. I didn't think much of it as I'm extremely obtuse.

Fast forward to a few weeks ago. We're both at work and have some down time. I realize I'm still attracted to her. We strike up conversation over random work related things and she starts asking me questions about things we like and don't like. Turns out neither of us like coffee and neither of us drink alcohol (or exceedingly rarely). Suddenly she states, "so there won't be any coffee in our house". I get the impression it sort of slipped out, but I can't really be sure. I don't know what to say after that so I change the subject and our conversation continues on its merry way.

About a week ago we're again working together and after finishing some rather taxing work we have some down time. We have lovely back and forth light banter and then I recall that there's a work-related dinner that evening that we were all invited to. I tell her I'll be going and ask if she is going. She states she recalls the e-mail but has had a long day and would much rather just go home and collapse into bed (totally understandable given our line of work). I head off to the dinner anyways that evening.

I really think I should ask her out more formally, but should I be concerned about her comment? Is she thinking too far ahead? Am I over thinking this? Is this a good sign or an indication of "crazy", so don't stick your dick in it?

Condense the text into a few key points
<bot>: Appears to be mutual attraction, but she made a comment that indicated she had already thought about marriage and beyond. Should I be worried?
