I'm a 29 year old divorcee (been divorced for just over a year) that is finally dating again. I've been seeing someone, who is younger than me, for a couple months now. He's a great guy and we have a great time together.

However, I'm wondering if our emotional maturity isn't matching up. Yes, I know there's the age difference, but I've had deep, meaningful friendships with younger guys before. (Note:this is the FIRST time I've dated or had any sort of intimate relations with a younger guy) I'm a very open and honest person. I love having deep, intellectual conversations. I love asking questions and getting to know a person. I'm a pretty romantic person too. I'm also a completely silly person, but I do like to emotionally connect more than anything.

Whenever I try opening up to this guy though or when I ask him questions like "What scares you the most" or even when I give him advice (on a mature and deep level), he always makes a joke. I realize this is a defense mechanism, but we've been seeing each other for about 4 months now. I casually brought this topic up with him once and his reply was "What do you want to talk about? Conflict in North Korea? I'm a dumb man. That's just who I am."

I don't think he gets it. I think he might still be scared to be vulnerable and I say this because a) He still hasn't officially stated he wants to date me and only me b) He jokes when things get serious and c) His last girlfriend was a bonafide nut job that screwed with him big time.

Just not sure how much longer to give this. I enjoy his company, but he's not ready to commit in any way, nor is he comfortable opening up. I've never had this issue with another person before... so I'm not sure what's up.
<bot>: Seeing a younger guy that doesn't seem to get I need emotional connection. Not sure if we're just not emotionally compatible, or if I'm not communicating what I truly need.
