i think my boyfriend is cheating please help

ive been with my boyfriend for almost 2 years and i really dont think he would cheat on me, but today he texted me at 7:19 and told me he was walking into work. then, i was looking at snap maps at about 9:00 (i wasnt looking at his location i was actually looking for my friend) and i saw that it said he was at his house 50 minutes ago which would be about 8:10. idk how accurate snap maps is but from what ive experienced its pretty accurate. i think either he’s cheating on me or hiding something else from me and i really want to believe he’s loyal but this just doesnt make sense.
