My 30 year old son has been married just 18 months (in this relationship for 8 years +) and over Christmas has told us that the marriage is over. No real reason apart from he has some new friends at work (including a younger woman who is apparently his new best friend) and they've been telling him he should be going out more and having fun whereas he and his DW (who is quite a home body) have been in a routine of staying in together. They are apart at the moment as she is spending Christmas with her family in another country but he is insistent that it is all over.
I am unbelievably sad. Although I want my children to be happy, I really can't believe he can just give up on his marriage so lightly and I just want him to try and work things out. I am worried that my feelings are coloured by the fact that my ExH walked out on me 20+ years ago in similar circumstances (I was not surprised when his 'friend from work' became his new wife) and to think of my lovely daughter in law going through what I did (although, thankfully without DC) is awful.
Is there anything I can do or should I just accept that he is an adult and support his decision (even though I don't think it's a very adult one!)
