My son is 18 years old and is set to complete his A-Levels in a few weeks. However, he is more focused on his girlfriend at the moment, and she is very keen on getting married and starting a family with my son instead of going to university. My son wants to study medicine and I don't want him to give up his dream for her, and having kids so young!!! I don't want to be controlling over his relationship, but I feel like he'd be throwing his future away in these circumstances. What do I say to him?
