Am I just being paranoid? Lived in our house (terraced) for nearly 3 years. The couple on one side are lovely, the couple on the other not so much, more an issue with the husband than the wife. He is outright weird and overbearing. Seems to think I'm a single mum etc, always trying to 'help'. Anyway, ever since we've moved in I've noticed whenever I go to the bathroom someone their side 99% of the time will go into their bathroom their side, I'm fairly sure it's him as she works 12 hour shifts. Never happens when my boyfriend goes to the toilet, and it's happening far too often to be a coincidence. Bare in mind I'm 7 months pregnant so if I go for a wee, chances are I need to go again 3 minutes later, and the person still goes into their bathroom. To begin with my partner thought I was being paranoid but since other stuff has happened he's now acknowledged it. Any advice?
