@clancaster154,
You need to talk to this fella more and less with your cousin.
To me it seems odd that he hasn't made romantic gestures to you. You need to ask him about this. ("Is there a spark between us, or are you just looking for a friend?")
There's nothing wrong with taking things "slow" but at least he could verbalize an attraction to you. In fact, you could say something like, "Do you like my hair up or down"? See what his reaction is. See if he even notices!
Really think about going further with this guy. If he is this shut-off verbally and physically, then what is he going to be like in the future? There's a reason why he's 30 and not yet in a relationship. These type of men drive their wives nuts.
