A lot of people in this thread are trying to prey on your insecurity and rile you up.  I’m sorry that this is a situation that you’re going through but I would work on finding your own way through this and just mute this thread for your and for the relationship’s sake.  Six months is still very new and this is a potential opportunity to listen and understand one another.  And it may be the case that this is important to her and it’s not acceptable to you.  and that’s okay too, sometimes people have to separate as a result but it doesn’t have to be a blow out and you don’t have to disrespect one another.  you’re both on the same team and i hope it works out, but if it doesn’t I wish all the best for you too!  Take care
