kade can do physical things but it's the emotional attachments that scare the absolute hell out of them due to his insane fear of people leaving him. so he tries to protect himself by keeping most people at arm's length which doesn't always work. or at all for that matter. i think he would have felt that emotional attachment to her and it honestly just scared him to where he just found everything wrong within himself and convinced himself that she absolutely deserved better than him. he definitely wouldn't have pressured her either, if things progressed he just went with it naturally. he probably still feels that pull towards her and probably still absolutely terrified of it.
