Would you be okay with this?

Your 16yo daughter met an 18yo boy. They’ve known each other for 5 months and have been dating for 4. You can tell they’re absolutely head over heels for each other. He builds her up and wants nothing but the best for her. He treats her like a queen and she treats him like a king. He asks you if he can propose to her, saying that she is the best thing that’s ever happened to him and that he doesn’t want to loose her, so he wants to take the first step towards making it last a lifetime. They’re both mature and have been through extremely shitty life experiences. Everyone of his family likes your daughter and your family really likes him. Im sorry if this is confusing. But as a parent would you be okay with it?

Comment why please! Thank you!
