how best to support DS, first big romance over

[catkin14]

DS & his Gf were together 2 years, now both 17 and she wants to expand her world (without him). He totally respects her decision but is devastated, she really helped him through my horrible divorce. He was close to her whole family and feels he has lost them.
6 weeks on now from the split he says all he feels is numb, no happiness or nothing.
I know (I hope) this will pass in time but how can I best support him? I wish it was as easy for him as kiss his knee and it will be better, but this was pretty full on for a first relationship and apart from talk with him when he wants to, I feel powerless to help.

Distractions...
Holiday.
Pass driving test.
New Hobby.

And just listen to him.

I remember going through this myself. Only time helped. Eventually I met someone else. Encourage him to get out and about and keep busy.

Thanks for help, we had a chat and he seems a little better, bit more positive.
Ex gf now telling him her life is wonderful (now that she is single) which was a bit of kick in the teeth for him but he is focusing on his job and whole life that he has ahead of him.
