Hey pixie
I feel your pain bud. i think if you have to cheat, get yourself a high class hooker. Go and F@ck the crap out of her once a month and pay her but dont get involved in a 2nd relationship.
Also, i guess you resepected your wife enough to marry her. Respect her enough to talk to her.
Also, make sure the hooker is healthly. killing your family by giving them aids is not cool
