I have a horrible gut feeling partner is cheating. The thought wakes me several times a night. Theres a few 'clues' but no hard evidence. Always on phone. Lock on phone that I don't know. Came home other night from work and jumped straight in bath which could be cheating could be he was dirty from work (didnt look it). Going out more but not to long, maybe 1-2 hours. Not a jealous or paranoid person. Im so laid back but something seems off. Sometimes he puts on this extra nice act which is just not him. Or maybe he's just being nicer. Want to confront him but know he will deny whether he is or isnt. But I just have a strong gut feeling....
