Yeah, Christians are hypocrites, just like the rest of the human race.
You knew she was a devout christian but married her anyway? Could it possibly be the case that you made a very common error of judgement? IE that she would simply be different once you were married?
Most of my friends got married years before I did. I watched with sadness as several of those marriages died. From what I could gather, there were unshared implicit assumptions.
SO, I sat down with my then fiance and worked out a contract. EG; no violence, absolute fidelity,no children , all money held in common.-------and a fat lot of fucking good that did. The marriage lasted 12 years before she left one day when I was at work.
As for the why of it. Depends on my mood when I’m asked. (if I deign to reply)
Right now, I don’t truly know. I have come to believe that when a marriage ends, any blame must usually be shared, even if unevenly. In my case, I wasn’t much of a husband and she was a cunt.
