I don't know how much to intervene!
DS17 met a girl on holiday 18 months ago she is now aged 18. She lives in Wales, he lives in Scotland. On holiday they chatted a lot, hung out together for a couple of hours most days.
When they came back they spoke on phone maybe weekly for a few months, then it seemed to stop about a year ago, 6 months ago, in the summer, he went to stay with her and her family for 3-4 days. Since then they send an odd message, not regular. He has been on a few dates with a girl in his school, he doesn't go out much at all with friends - if he does it is to do an activity with those specific people, eg never to social situations eg to a pub.
She went to Uni close to home, she is close to her family. He applied to 4 Unis, one is the one she goes to, it is not unreasonable to study there, but would cost more, is less nice place to live, he has never been and has no tie and connection, other than she goes there.
All along DS has said he wants to go to Uni locally, adamant he only put the other place down as it was a good option - but with no evidence as to why it is good. Financially and for support staying in Scotland makes sense. He is doing a 5/6 year course.
Now he says he is not sure where he is going, but I know he is deciding to go there. Reading between the lines, she has said (some time back) there is no future in this relationship as we are not in the same place. He does not want to discuss it further.
I am prepared for him moving away. But if he is moving on the chance they can get together, paying tens of thousands to do this. Talking to him so far not helped. What would you do?
