will cheating ever be revealed?

i always have a strong feeling that my husband is cheating on me. all the signs are there. hes secretive w his phone, bank, money, and email when he was open to it all 2yrs into our marriage, thruout our dating times. he goes out a lot, sometimes stays for the night, he goes in another room to touch his phone, a lot of things. i just need proof thats all. ive talked to him about this many times, but it always goes bad. itll just end up w me being the problem, hed say im only trying to ruin our marriage. yell at me and act furious to shut me up. i am now just waiting and hoping for it to be revealed to me. but im also tempted to snoop, because if i do find something, i will leave, regardless. yes, it will hurt, but i rather be crushed by the truth than get hidden from it. i rather face the truth than live a lie. i cant snoop tho, cause its fingerprinted lock. i got signs hes cheating, but i just need proof.
