| | Re: The effects of pornography and Facebook on a marriage
Facebook and porn aside, the fact you haven't had intercourse in 6 years is a ginormous red flag right there. I would say you have HUGE intimacy issues, which he turns to porn to deal with and you turn to other people, which right now is another man, which is going to lead to you cheating if you haven't already done so. EA at least.
I've posted my view of porn elsewhere, but I don't see men looking at porn as a huge issue in itself, in an otherwise healthy relationship. Which yours does NOT seem to be.
