What does this mean?

I've been talking to this guy and things are going okay. He's a great guy. But i seem to like him more when we're away from eachother. And i like him but it's like when we're together i dissociate a little bit.

Like it feels too intimate and i feel like i step out of the conversation, like I'm not in the moment.

But it's like i love when we kiss and hug and hold eachother and have sex. Even when we text i like it but it feels everytime we're in person actually talking, my heart and emotions are not completely there.

Feel free to ask me any questions. I'm just trying to figure out what this means
