My girlfriend of 6 months moved in with me 2 weeks ago(yeah, I know). She is nice, caring girl, takes care of the house, cooks, does laundry etc. I maintain frame, workout, have rich social life, study work etc. Last week however I was ill and couldn't really leave house. I didn't go out, workout or study, I was just chilling in bed, trying to get better. Well, yesterday, I went out with my mate and 2 of his female friends(My girlfriend was out as well, with some of her university friends, males and females). We came back around same timestamp and she immediately started asking me questions. I told her I was with my buddy and his 2 girlfriends, she started asking me specific questions about the girls, their names etc, I laughed and just brushed it off, ignored this shit and fucked her good later. Well today she is having some kind of a bad day and starts the topic again. I explained to her that I like our relationship but it's not priceless for me, im not going to let her control me and I wont tolerate her shit. Well she says that she is sleeping at her friend's house today(that friend is kinda sluttish). I say fine, you can take your stuff and move out. She says ok, thursday I move out if that's what I want, I told her that's not what I want but I'm not going under her control and she can take her stuff even tomorrow, why wait for thursday. Did I handle it right? I'm certain that she has strong feeling towards me, I like her a lot but im pretty sure I dont love her. What should I do?
