Hi. My daughter told me and her mother over dinner today that she is dating someone. She then told us that he is 20 years old, in 2nd year of university. She is 16, in grade 11.
I have a 17 year old daughter and an older one. Neither was allowed to date. They aren't capable of dealing with the consequences and I pay their bills...including extremely expensive tuition. 20 year old males generally have sex. So simply ask yourself if you're ok with your 16 year old having sex with the guy regularly and potentially there being serious consequences out of that...STDs and pregnancy. If you're ok with it and think she can deal with it...then let her continue doing it. If not, set the rules since she lives in your house. That's something you and her need to discuss in detail.
