Possibly cheating??

Would you find it weird, if your so all of a sudden started shaving his pubes?? And never put his phone down/always keeps it in his pocket, when he usually wouldn't care he would just leave it anywhere, and now he just complains about where and how you sleep, (I sleep on the edge of the bed close to the phone chargers). I don't want to go through his phone what so ever. I don't know what to think or how to even confront him about this.
