My boyfriend mood changed a lot?

so at home he is so sweet and caring

At work he is different, we work together, he doesn't touch me or kiss me

We went to a swimming pool he plucked a flower for me... how cute is that?

I was surprised since he is so cold and shows 0 emotions, barely touches me

I want him to make more of this cute romantic gestures, how?

Also we dont live together yet.
