<human>: Condense the text into a few key points

My bf and I have a passionate, loving relationship of 3 years. We're both in our late 20's. We don't fight much and we fight fair, but afterwards, he puts up a wall. 

The wall looks like this:

* One word answers

* Lack of verbal affection

* Reluctance to see me

* Lack of physical affection

* Ignoring me

This time, the wall's been up for weeks. Before anyone says the easy answer: "He wants out", I've tried to leave and he does not want to end the relationship. He's a straightshooter, always says what he means. So "break up" isn't helpful here.

He's a sensitive person, usually self aware, and has said the wall is out of fear and protection against pain. It's just so hard to be with him when he does this.

I'm not really looking for advice for me. I can cope with this for a while. I'm looking for advice for those who wall up this way. That's not my way and I don't know what the best thing to do is to help him. It doesn't seem like this wall is making him happy.

So fellas what helps? Space? Fun together? Talking it out? Certain responses from your SO? I really want to get back to the place where we can enjoy each other again. Since I've been through this before, I'm trying not to "read into" or take it personally.

So if your wall is up with someone, or around someone, how do you want them to treat you?
<bot>: BF emotionally walled up after a fight. He wants to stay together and wants wall to come down. I do too. How can I best approach and treat him to help?
