Whenever my girlfriend invites people over to our place without telling me first I get really upset. We've already had several conversations about this and I've established that i need to know who is in my space as a boundary several times. She was telling me whenever she would bring people over for a while and it was great until this morning I woke up to 2 of her friends in the living room cause she thought they would just hang out and leave before I wake up. I hate being upset about this but I hate feeling like she just doesn't care about my boundaries and what I ask her to do. It reminds me of my ex and how every time I would ask him to do something he wouldn't and we would argue about it a million times. I don't like being upset with her but I don't like when people dont listen to me or care about what I've asked them to do. Does anybody have any advice?
