What are V plates?!
I understand. My son started dating at 14, whereas I was at uni and finally just dated the next person who asked .. I thought I'd end up alone forever if I didn't!
Anyway, I digress.
I thought he was telling me a lot (as in neither of them wanted to have sex yet because they were both freaked out by the idea of unwanted pg). But it turns out she wanted to know where he was every moment of every day. I didn't even realise because I haven't dated since the Nokia, and he was under the impression that it was entirely normal to be in life 360 and in touch every half hour.
I felt awful because I didn't realise she was being really controlling the entire time.
So I would say appear to be entirely uninterested, but keep family rules of no texting/ distractions for x occasions, such as dinner etc.. and be alert. I'm sure if I had a girl I'd of seen it differently. It didn't occur that a bolshie boy, built like a brick barn, could end up in this situation, but now I know.
They broke up, and he's now got a really lovely girlfriend, and I'm actually worried because she's been raised in a pretty religious household, and I suspect thinks he should be in charge. I'm keeping an eye out for both of them, but at very much arms length.
