My DD is 19 and has just finished 1st year uni and is home for the Summer holidays. She split up with a long term boyfriend (over 2 years) last summer before they both went away. She has been doing a lot of OLD; very few have got to date 2 or 3.
About 6 weeks ago she went on a first date with someone who dm'd her on Insta. They have mutual friends. They have seen each other maybe 6 or 7 times since then. She is wanting him to now to stay over saying she is an adult and she has had a year at uni being able to live as she chooses. This is not a confirmed or committed relationship yet and what will happen when she returns to uni in October has not been discussed. Whether either or both will not really want a long distance relationship is debatable.
She thinks I ABVU to say that I'm not keen on this as it is so casual. She gives me long lectures on sex positivity and accuses me of slut shaming. She is very good at arguing and I feel I am being browbeaten. AIBU or is she?
