Its wrong IMO either way. If your going to cheat or feel those urges, have some class and either tell your partner how you feel or leave the relationship first. I found out my wife had an affair 3 months ago and blames me for it. I accept my part in having a not so desireable marriage, but I cant wrap my mind around her having an affair. Its like someone dropped a bomb on my head...it sucks...She says she is Christian and in all her emails to the other man she and he would quote scripture! HA!
