My ex is deployed and we are getting back together and I'm often nervous he might have met someone or slept with someone but usually when he assures me he didn't all that worry is lifted. this time I was absolutely convinced of it for a day (sort of baselessly) because of his attitude, and I've never heen convinced of it nearly that strongly before. He assured me he didn't and was nice but I still have a bad gut feeling, which has never lasted after reassurance before. Does that mean something bad, or is it just leftover emotions/fear from how strongly I convinced myself of it?
