Hubby ("Z"/45/m) of 8 years' friend ("J"/44/m)'s wife confided in him that she ("L"/38/f) and J are having marital problems over Facebook and are in "couples' counseling" in California. The couple is now in Hawa'ii, where J cheated on L again. L has since left him to return to California and weigh her options. They have 2 kids, both his.

I fear Z may cheat on me, if we were in California. However, we're in London. However, this does not discount the possibility of an emotional affair. Any thoughts, fellow RPWs?
