Guys: Do men need space when they get overwhelmed by feelings?

Guys, do you get overwhelmed and pull away when you start having feelings for a girl if you don't feel ready for a relationship, or still getting over a breakup for example? When you get a bit confused with your feelings, do you act "hot and cold" and even avoid contact with them?

He ended a 2.5years long distance relationship cause things got cold and the girl didn't want to move to his country anymore, so he was heartbroken, but didn't want a relationship without purpose so he ended things. He said he would never do long distance again.
We rekindled a flirtation from the past a bit after cause i was visiting his country in 2months so I arrived there and we were together 4 times, but I was another "long distance" fling. He would be hot and cold. Sweet and then aloof.. wtf

We would have amazing sex and chemistry... I felt the intimacy, the "vulnerability"... and then after sex he would shut down and become aloof and distant. That bothered me and we had some arguments about it but he would always text back and act like he cared, only to be weird again later. To the point of not even kissing me anymore when we were not being intimate. It bothered me obviously. When I was leaving he sent me a cold farewell text. I replied thanks and it's been 12 days no contact...
