New here but been RP for about 2 years. I’ve been in an LTR for 8 months.

Last night my LTR and I hosted some of her friends at her apartment. Everything going well. Normal night. The girls from the group start talking about their previous sexual experiences at the table.

One of the girls asks my LTR if she ever slept with (random guy they all know from the past name here). She replies “Yes. In high school”. I quickly interject and change the subject and the evening goes on.

Everyone leaves and I tell my LTR that I was pissed off and to never speak about any previous sexual experiences when she is with me in front of people ever again. She says she doesn’t understand why I am so upset. I tell her I found it disrespectful as fuck and this will be the only time this ever happens. She apologizes and we go to bed.

How did I handle this?
