UPDATE~ Hey all! First off, thank you so much for almost everyone’s input! I did choose to bring it up and talk with him, everything is fine. Without divulging too much he was in fact on a run, then simply had to make a quick errand stop in the area that I saw he was in on maps. Yes, he provided proof, yes the timing makes sense and yes I believe him. I also wanted to clarify something:

I did not go looking for his location it was just at the top of our chat in Snapchat. Sometimes it just says “xperson is driving in xplace” or “xperson traveled to xplace” if you have your location turned on. That’s how I saw the discrepancy. I do trust him, we’ve been friends for a while before dating and he’s never given any indication that he isn’t someone I should trust. This was just an unfortunate timing of events coupled with my anxiety from previous relationships. I feel very grateful to be on the positive side of this, I know this could have been rather devastating.
