is God trying to tell me something?

my husband has been doing suspicious things that could lead to him cheating on me. i also have a feeling hes cheating, so i prayed to God, and ask him to reveal it to me if my husband ever cheats on me. i told him my only hope is in him, talking to husband wont help, snooping wont do it, these signs dont really tell much. after i was done, i went to clean, and i saw a long, blond hair on my husbands coat. i have black hair and none of mine or his fam has blond hair. i feel like this might be God trying to tell me something or hes just making me go crazy, which i already am cause i see all the signs, but i have no proof. i cant just accuse him, what if he isnt cheating? i cant talk to him, he wont reassure me, and hed just make me the problem. what do u ladies think?
