My partner and I share locations. We check sometimes how far away from home they are when walking the dog, or coming from work. Also handy when one of us “loses” their phone and the other can see it’s at home/in the car/at work. But we have trust, and don’t need to check where the other is spending time.
All they would have to do is turn location sharing off, and change passwords. More likely they would talk about it and agree to split rather than just run off. You know, like adults.
