Does my female coworker likes me or what? Need advice?

Anonymous
We've known each other for 7 months (she has a boyfriend), she shares her food, we ate together, she even tickles me everyday and then one day she got moody , she became silent but talks to everyone in the office except me, like i dont even exist. So i got frustrated i dont know what to do since i have no experience how to handle that situation, i have no girlfriend since birth, so i became distant to her for 2 weeks ( very awkward) ... But this past few days she just sat beside me at the cafeteria, we had a casual conversation but never mention why are we not talking to each other for the past few weeks.

This where i need advice because everything is changing
And i dont want to assume that she likes me. But everyday is a bit more confusing she's behaving different,

-When She asks me if i already ate, if not she insist that we eat together.
-she has this touch that rubs my arm for a second
-our legs brush often when im on her desk or in a meeting
-the tickles became tripled
-she invited me last night to have dinner before we go home
-now she's asking me if i want to go with her this Saturday to a mall
- a lot of eye contact (uuggh)


But she has a boyfriend (5years)
