Am I in the wrong for spying?

[no mercy]

this is NOT ok to talk to exes and other women if it hurts u. but it is never ok to spy on him either. what re u going to achieve by doing this? what u don't know can not hurt u. anywho, a GROWN UP people would handle it this way:
you: I do not like u talking to your ex and other women on facebook. I am sure u won't cheat on me but I do not like u wasting your time on talking to them, it is not loyal to me. I prefer u to roll in bed and talk to me instead.
him: ok, baby, I did not know my actions hurt u. I will delete my facebook account and block my ex's number and email
this is how GROWN UP and mature people handle things: u inform your partner that his actions are hurtful to u and he decides he does not want to hurt u so he stops (of course be reasonable with your demands). but if u tell him him talking to other women is unpleasant for u and he tries to justify his behaviour and does not stop and u start spying on him - totally wrong on so many levels
