re: OM and your concerns about infidelity. Reading your thread, you bounce around a bit. First, you told us you had "proof", then that your friends believe you're prone to see "proof" of infidelity when it's not so.
Qs - Do you have undeniable proof of an EA or PA? If not, how strong is your evidence?
Qs - About being prone to imagine infidelity--are your friends right, and why do you think they believe that?
Affairs are common here--just trying to better understand your specifics.
