Does my colleague like me?

So I have been working at my current job for 4 or 5 months.

One girl everytime we seen each other around doesn't matter if it's the 20th time in the last few hrs she will say "heyyy"

And from my observations I am the only one she acts like this too she will say hey or hello to other coworkers but only the first time she sees them the procedes to go about her buissness.
