Should I say ?

My liking for S is growing stronger as each day goes by...I even dreamt of S the other night...

We do get along well ( at least in my perspective ) at work and I enjoy her company ( and hopefully she enjoys mine too ). Last Wednesday we had a company lunch. I was already struggling to "let it go" so I intentionally "avoided" her at work. However, we still end up being in the same table and she sat next to me.
We shared small conversations in close proximity...I really enjoy being close to her but I was also careful not to let my feelings be obvious.
