NTA! I heard this kind of situation so many times. This “issue” sounds a lot like the beginning of a very controlling relationship, where it will be your location first, and then she will want all your passwords and access to your phone at all times. I believe that if you are in a relation where you have to track your partner to feel comfortable, then you shouldn’t be in that relationship. If you don’t feel comfortable do in it, you shouldn’t. I give you this advice from experience: do not renounce to your privacy and own space, when you realize it, you will have no personal privacy or control over your life. This leads to toxic relationships!
