My niece is 16. A really sweet girl who is doing well in school and is bright and popular. She's started seeing a guy who's 20 almost 21. I've met him a few times and he seems nice, works full time and I think treats her well. I don't know if they're having sex yet and don't want to push her away by asking.
He's also a bit of a party guy according to some people (small town gossip grin) but nothing really bad.
I look out for her and I just feel a bit concerned with the age gap. She's not very experienced and is mature in some ways but I think quite naive in others. She's planning to study at uni next year and I don't want anything to put her off. When I was her age I was hanging out with older blokes, bunking off, drinking etc and I don't want her to mess up like I did. Her mum (my sister) has asked me what I think and I honestly don't know?
Would it bother you and what, if anything should I say or do?
