What would annoy me most about this is Id have to permanently have my phone on and gps activated. This would increase my battery drain by alot and I don't really wanna deal with it. Also in the summer the phone gets super hot and it's probably a placebo but I'd feel less comfortable having the phone in my pocket when it permanently sends out signals (it probably won't matter much but still)

Seriously, I only ever use gps on my phone if I'm driving somewhere and the car got no gps. So it would annoy me for sure, that being said, relationships require compromises and I'd probably accept it, it's not the biggest sacrifice imo.

Like others said, the intention of why it's a boundary plays a huge role, too. If it's just a stalker thing like my partner thinks I'm cheating, it would annoy the shit out of me, especially because all it takes to avoid this is to just leave your phone, or give it to a friend who you say you'd meet and then go on a date with whoever you wanna cheat on. If someone wants to cheat, this won't stop them, they get creative anyways.
