IrishDad, do by all means produce the properly-conducted research that suggests Irish woman are 'happier in their marriages'.
You seem to be taking the reasoned arguments that there are all kinds of reasons why there is a lower divorce rate - later marriage, more unmarried cohabitation, the length of time it takes to get a divorce in Ireland, those Catholics (mostly older people these days) for whom marriage is an indissoluble sacrament, making civil divorce an irrelevance, because they would not be able to remarry, property prices, negative equity meaning people are literally tied together etc etc - awfully personally. Why so chippy on this issue? And why on earth do you get to speak for all Irish women?
And for the record, I tend to approve wholeheartedly of the vast majority of the situations where Mumsnetters agree that a poster should seriously consider ending her relationship. These are overwhelmingly either situations of physical, financial or psychological abuse, repeated infidelity, or - in a new relationship - full of indications that the relationship is likely to be unequal and unhappy for the woman. In many cases the poster had put up with an appalling situation for some time, and is too cowed and/or brainwashed to leave or self-esteem too battered to think she is worth more than the minimum.
Offred, that isn't actually the case. I am an atheist who could not be more critical of the Catholic church, but divorce doesn't condemn you to hell by any means from a Catholic hierarchy pov - it simply means you can't remarry in a Catholic church, and that any subsequent civil marriage isn't recognised by the church, unless you also get an annulment. It's by no means a liberal position - if you are a Catholic who marries in a Catholic church first time around, divorces, and remarries in a civil marriage, you are not supposed to take communion until you have gone to confession and promised not to have sex with your new spouse! - but it's hardly hellfire. You've committed no sin if you were divorced against your will.
On other issues such as contraception and abortion, I would fully agree with you.
