So I met my 17yo dd's bf yesterday. He seemed perfectly nice and I don't have any problems with him. I didn't meet him for long. However a couple of times my dd was pretending to not know something I'm pretty sure she did and also she was laughing at a few things he said that just weren't funny at all. Also she got really scared about a spider and she is not scared of spiders normally at all and it was really unlike her. I just got the impression she really wasn't being herself around him. I spoke to her about it later and she said that she was trying to make him feel good about himself and that I didn't understand men at all hence why I've been single for 12 years and told me not to give her advice on that. I'm not sure what to do as I really want her to feel like she can be herself and not play up to what she thinks is attractive. Normally I would definitely not get involved and I am generally a very chilled out parent. Obviously she is so young now but I worry this will continue as she gets older and I just want her to know she deserves to be in a relationship where she can be herself. Not sure if I am overthinking this and thinking it is a bigger deal than it is.
