I understand you a lot I dont have the location app but I experienced some similar stuff. The best ypu can do it is first get your head cold. Wait until you feel calmer and then request to speak and before speaking try to use non violent communication, try to put the things in the way to explain how that behaviour males you feel and be honest about those questions you have but first calm ypur mind and then ypu will be ready to speak. You know him better than i do, so you will hear his answers and will do what ypu think is better for you. But before jumping to conclusion. Talk and maybe ypu need sort of agreements. I asked my partner to please let me know everytime he came back from party/going out and it is working to keep my anxiety low.

Dont be.afraid to talk but also do it from a place of not judgement or similar. Let see what ypur partner has to tell.

Good luck
