My DS has been with his partner for five years. She wants to start a family but he says he isn't ready to commit to that. They've discussed it and she's told him that she wants a break from the relationship to decide what to do. He's told me he feels 'very, very down'. He's recently started a new job living in London, earning good money but in a career that he dislikes, while she's remained in their home eighty miles way. He's texted me this morning and wants to talk to me but I don't know how to advise him. It's not just the issue of their relationship, but the fact that he seems to have a fear of commitment to anything or to anyone and is getting depressed about how his 'life has turned out' (his words).
What can I do or say to support him?
