Questions: Family & Friends

I told her there was no need for her to know about the plans i had for tonight untill i knew for sure it was happening. There was a big chance it wasn't gonna happen and yet because i thought i could trust my hairdresser she blabbed to my mum, then mum kept making comments claiming i was over reacting and he couldn't possibly like me? She even tried to make out i was making it up And no such person existed and she made other comments too like they were digs. She tells me Not to keep secret s but what does she expect when she interfers.. She knows this guy and most of our family know him (i dont think she knows who the guy is tho) but im not an idiot i do my research as much a si can. All i wanted was a drink in the pub we'd already been to, nothing else. Yet it appears from Them im Not allowed this at all? she's always been like this interfering in my business and getting too involved. Even with my brother she's like. "yes go out with this girl when the kids are at school and dont introduce them to her" etc like he's a child and not a grown man
