Can I be brutal? This is meant with love, but stop and think:
1) he is alive, happy and healthy
2) The world is no longer a big place - and if the "usual invitations" have been extended it is up to you to accept and go to visit
3) from what you say about your daughters being near, I suspect you could feel just as lost if he lived at the other end of the country where he would also no longer be part of your everyday life in the way your DDs are
4) boys/men are notoriously bad about communicating - you need to get to know his new girlfriend, welcome her into your famiy and she will make sure contact is maintained
5) however hard it is to accept, once our children grow up we no longer feature in their lives in the way we did when they were children, something I came to terms with when ours went to university, but if you try to hang on too tightly, the only way is away
Many parents have sons and daughters on the other side of the world and I can imagine how heartbreaking that must be, but our children have to make their own way in the world and if that is abroad, so be it. My Mum came to this country in 1947 not knowing whether she would ever see her parents again - it was a risk she was prepared to take, but how must they have felt?
I can also just remember the stiff upper lips giving way when they and I waved my sister, BIL and their 3 tiny children off to Canada in the 60's.
I hope you can see that geographical distance is not the issue it used to be and if you are fit to travel, you must go to them and not wait for them to come to you.
(Here endeth the lesson!!)
