DS is 22. He's always been very private and hated us knowing anything about his friends. We met his last girlfriend who came for dinner several times, no problems at all. He now has a new girlfriend who works with him. He brings her back after work and keeps her in his room, emerges late morning to bring her a coffee. He doesn't have an en suite so she must at some point need a wee or want to brush her teeth but we never see her. Then we hear the front door go and they're gone.
This morning I said he should allow her to roam the house freely and we would just say hello. He said, no we're going out. I explained it's rude to keep her in his room (which smells like teen) for her and for us. I heard the door go about half an hour later.
Is it me or is this not on?
