Straightforward: my 29-year-old son is dating a 16-year-old girl he met at a jazz festival this summer. Openly. He had a same age long-term girlfriend until last year, when they broke up amicably. We really loved her, she was basically our daughter-in-law and we’re still in touch. His current girlfriend’s parents know about their relationship & are cool with it. For the record: it’s also legal in our country. We don’t think it’s right though, he’s a grown ass man while she’s a high schooler. He’s also very successful professionally, handsome, takes good care of himself, has a good personality, etc. so it’s not like he’s lacking options. He just says he likes her - that’s his why. He’s not a bad person, I know that, but still this whole situation has changed our perception of him quite a bit. We’re having a rough time to say the least.
And comments like yours are the exact reason why he probably feels like he must protect his inner child against all odds. From what OP tells us, he has his professional life under control, so let him spend his free time however he wants. See my other comment for details.
So you think 16 is a child?
Never said that, never meant that.
When I said “inner child” I meant his own capability of leaving his adult responsibilities behind for a while in favor of doing things that society as a whole deems childish. Indulging in certain hobbies, acting a certain way. I can’t find the right English word right now. In German we might call it being “unbeschwert”, so maybe “unburdened”.
I was specifically replying to the passage that he should have spent those 13 years in age difference growing as a person to an extent that he shouldn’t have much in common with a 16-year old anymore. And to that I ask: why? Must every adult be a joyless, mindless worker drone who can’t enjoy the things they enjoyed when they were 16? I’m happy to discuss if the relationship OP described might be problematic because of a power dynamic and that’s been done to death in this thread. But saying he isn’t allowed to feel connected to someone younger than him based on shared interests or a need to escape his adult responsibilities for a while feels bitter and judgemental.
None of this has anything to do with me labeling anyone as an actual child.
