so i recently started talking go this guy from work and we have hung out a couple of times, whenever we hang out we always go for walks or just hang out at his house. we've never kissed or cuddled while watching movies or ever mentioned anything to eachother about whether or not we had feelings towards eachother. sometimes when we're laying down he'll have his hand on my thigh or rubs my back and sometimes it just gets me in the mood but he wont do anything and neither will i. what should i do? how do i even know he likes me?
