Sketchy boyfriend ?

My boyfriend has been acting very secretive lately and I just want to know what I should do. For example, he works at a car wash. Today, I was going to look up directions on my phone and his icon (he has location services on so I can see where he is/he can see where I am) was in a neighborhood in a city completely different than where he works at. This isn't the first time either. Should I ask him what he's been doing there?
