Video - Trust Issues Resurface: AITA for Suspecting My Husband Again?

AITA for accusing my husband of cheating? Let me start off by saying that my husband has cheated on me in the past. We agreed to go to couples therapy and I gained trust in him again. Recently, my husband has been leaving the house mostly around dinner time. Everytime i check his location, he's at a restaurant or a coffee shop and then when he comes home i always have dinner ready but he's never hungry. I let my curiosity get the better of me and i started calling his friends, all of them told me they weren't with him and he hasn't asked them to make plans in a while. I've been trying to go through his phone, but he's always so protective of it, grabbing it whenever i get close. So, AITA? Should i trust my husband? Am i overthinking this?
