@simbobs, really sorry to hear this. I had wondered if DS was unhappy, but I think he is OK, just wanting to see the gf.
Yes, if he is even remotely interested in footy (or rugby, hockey, etc) there is probably a team for him - DSs college alone has 14 teams and the footy club is about 300 boys. I think most of his new friends are through footy. And there is most definitely an active social life.
Shame he hasn’t found friends yet - he can still make new friends though. DDs bestie from home only really met people she clicked with in the second term, but she did have to make the effort to put herself forward and join more stuff.
Where is he studying again? I am so rubbish at remembering
