Communication is everything...Especially the early days...How do you feel if what you've said above lasted the next 6 months/year/two years....?

EDIT: It occurred to me, is he jealous of your previous partners and his saying you're not at peace is him saying he can't deal with it?

He sounds like a normal guy who initially was free to talk about himself but once things seemed like progressing further, took stock, became self conscious and pulled back a little/lot.
Might have frightened him with your candour and he does not know what to do with it. Getting cold feet, he may be over thinking it as well. Inwardly. You know guys and girls think totally differently on almost all topics especially relationship stuff. It is scary stuff. Might be unknown territory for him and he is floundering. Do not expect too much. Accept him for who he is and do not pressure for emotional responses.
Always difficult to find someone compatible, not flawless, because they do not exist, compatible is good.
This can work, without pressure, unless you need/require an emotional communicator.
Working people do live in a different time zone and have many things occupying their minds/time.
You will not be on his mind 24 hours a day. He is busy with work, work politics. He may have a whole lot of pressure weighing him down but he is not going to open up about that. A huge proportion of the population are under huge stress but they do not off load on their loved ones/partners.
Not much more I can say. Wish you well. Do not expect too much, and do not pressure him to open up. He will if he wants to/ready to.

I was in a similar situation, but I broke it off. She was the emotional one, I was the logical one in the relationship. Long story short, if you're no longer happy and he's not budging, move on. I did and it was the right thing to do.

It sounds like you need to decide what you really want.

Sorry tltr.

Just stop being a bitch.
