Am I in the wrong for spying?

[Carrie]

I am so in love with my husband, we have been married for 4 yrs now. I know he loves me and he's a good guy he never goes out to clubs and I don't really think he's cheating on me but he's done things to make me wonder and be paranoid that he might, like I've caught him talking to ex's and other girls on facebook nothing sexual but it still made me worried. I've even caught him doing that poke button to random girls. Anyways we've got in a lot of fights over it and he swears he never met up with anybody and he swears he's never cheated on me he even gave me all his passwords. But I still worry so to ease my mind I put easy logger on his phone it records all his calls and texts. It's a free app so I'm not paying to spy and it actually works great. I mainly did it to stop worrying. It's only been a couple days so I haven't seen anything yet and I don't really expect to, I'm actually trying to prove to myself that he's not cheating... Is this wrong of me?
I honestly wouldn't care if he spied on my phone because I know I don't have anything to hide
And so what u guys are say is that it's ok for someone to communicate with their ex's and flirt with other women online when they're married even if it hurts their wife? And makes her crazy? Then she's in the wrong for worrying and spying?
