Coping someones actions?

My crush copies sometimes my actions, like if I brush my hair away from my face, they would run their fingers through their hair.

If we go for drinks and I lean forward to rest my elbows on the table, they would do the same thing.

When I feel a bit sad, they also look sad.

If I rest my hands on my lap, they would also rest their hands in their lap.

If I drink, they would copy and drink at the same time as me.

Does this mean anything?
