My partner has invited a close friend to stay with us in a week for 2 nights and 3 days I've never met or spoken to this friend, I have no jealousy or hate towards this friend as I fully understand the friendship, however I feel really uncomfortable that she will be staying as I'm very introverted and I hate my personal space invaded by someone I've never met I've explained to my partner I'm going to really struggle with it as her friend is very social and chatty I'm not sure if I will deal with it very well or even want to stay at home I'm looking for advice if I should be brave and deal with it as it'll make my partner happy, should I try and find a way to be away from the situation or deal with it and try and get along with her friend?
