he’s said it was pure strange & weird and feels pure awkward being friendly with me now. I asked what he wants to do and he said he doesn’t know but he won’t be rushing for a night out with me and he doesn’t need this right now.

I think you should just take what he’s said here to heart and leave him alone completely until he contacts you. If he never contacts you, consider it a friendship that has ran its course.  I read above that this is a different guy  from last time, so it just seems like you get really attached to people, so that might be something for you to work on about yourself: allowing people to come and go from your life without getting too upset when the friendship has run its course and they move on.  I’ve had many friendships that come and go and come back again later and then go again and come back and some that stay gone, and that’s just sort of what happens with adult friendships and even romantic relationships.  You have to learn to be okay with going with the flow of relationships because when you try to hold on, it pushes people away and decreases the chance that they’ll ever come back again, and some people really are just meant to be temporary friends.
