Am I being crazy?

So I just got off work and I get home to my boyfriend it just seems weird, he seems weird. You know how girls have the intuition and gut feeling. I feel like someone was in my room that wasn’t supposed to be the energy is off, if you know what I mean. Should I question him or let it be? We have had cheating problems in the past that’s why we broke up for a few years but we’ve been together now for a year. So should I say something? I need answers before he comes out the bathroom and he’s been in there for a while. I think I should trust my gut and go for it.
