My DS is 14 and told me this morning, very casually, that he has a girlfriend and they've been together for a few months. He's a really lovely boy: smart, good-looking, very grown-up and sensible but fun, emotionally intelligent, kind, interesting and funny. We talk a lot about stuff, he seeks me out to talk to about loads of things, he's great company, but I had no idea he was properly with someone. He roams off with various combinations of friends at the weekends for a few hours but I didn't know a specific girl was involved. In fact, I'd assumed he was gay because of various conversations a couple of years ago, which would obviously not be an issue either. I have wondered if he was in love with someone for a while, though, mum spidey sense or something. His girlfriend is a friend of one of his oldest female friends (who I know really well as they grew up together, and who only has good people around her) and she is almost a year older than him. He says she's just like him. She's sounds lovely and I'm over the moon for him but obviously playing it quite cool, no pressure or interrogation, just said that's ace, I'm so glad he's happy, and she's very welcome to hang out here etc. Her parents know about him (which is definitely the right way round).
My AIBU is that DS doesn't want his dad to know yet and has asked me not to tell him. Am I being unreasonable in respecting this?
DH is a complicated person, he can be extraordinarily kind, thoughtful and generous but can also be a bit Victorian Dad (orders, demands, tellings-off, frustration, demanding respect) and also defaults to teasing and piss-taking around me and our teenagers. He wants to be closer to them (we also have an older DD, who hasn't got a boyfriend/girlfriend yet) and for them to talk to him, but they hold back because he can be a bit insensitive and immature, tbh. I completely understand why DS doesn't want to deal with his dad's reaction (which I actually think in this instance would be good and sensitive rather than annoying and crass, but you never know with him).
Should I tell DH at some point soon? With or without DS's permission? Or keep quiet for the time being? Or suggest DS finds a way to tell his dad himself? I know this sounds like a small thing but I want to get this right for DS and don't want his relationship with his dad to be worse as a result.
