<human>: When I'm around her I get the feeling that she does like me, but then when I'm away and over thinking everything, I feel like she doesn't and that I'm making things up in my head.

There have been some moments when I've been 100% sure... like when we kept making eye contact, sometimes 3-4 seconds, with smiles included and I could feel the mutuality.

We do tease each other too... We've only started speaking 2 weeks before the holidays. We haven't seen each other over the Christmas period though and she finished a relationship not too long ago too.

Can you condense the text into a few key points?
<bot>: Really like this girl on my course. I'm sometimes sure she likes me back, but then when I'm away I talk myself into thinking she doesn't :( Need help.
