My ex's location is visible on Google Hangouts and I'm gonna watch it like a hawk.
Does he know you're gonna do that? I really hope so.
Yes, I told him I would do it.
Well, as long as you have his consent, then I don't see an issue with it. Just be responsible.
Even if I didn't have his consent, I would still do it.
Stalking someone's location, even just via an app, without their consent is wrong. At best, it's creepy, and at worst it can be seen as stalking and harassment. Even with his consent, I think it would best if you didn't do this since you should let him live his life how he wants.
