Ok need to clarify a few things. I live in a very rural part of Northern Ireland, so actually in UK. However, i grew up in Dublin, and i can honestly say that the area i live in now is a hell of a lot more conservative, religious and socially judgemental than Dublin city is nowadays.
Any divorce here in this small town would be hugely difficult on the children, it would be talked about for ever, they would be subjected to a lot of scrutiny, judgement, and just plain ole nosiness really.
For myself, if it were just me, i really couldnt give a shit about what people think of me round here. I am not a religious person, in fact view myself as an athiest now, and have progressive views on marriage and divorce etc that would not at all tie in with the norm of thinking around here. So my aversion to divorce is based on the social effect it would have on my kids as well as the emotional difficulties it would visit on them.
I do realise that living with parents who are not really together, in the real sense, is not great either. But i look around me, and i know many couples with kids who live like that, and the stability that provides their kids is better than the disruption and social upheaval i have seen caused as a result of divorce around here.
If i lived in Dublin or any other large urban area, perhaps i would act differently. But taking all things in to account, this is a better solution to my mind, not perfect, or ideal, but a lesser of two evils.
my dh is from this town, and is extremely aware of his image and standing in the town. By taking my own life into control, doing what i want, choosing not to do things with him that i dont want to do, i feel i am taking back some power. It will embarrass him massively, and social embarrassment may work to change his behavior in a way that pleas from me never have done so far. For eg, even me not going on this trip to Barcelona and being upfront with my reasons for not doing so, to this other couple, will hit him hard.
I, on the other hand, get to suit myself.
As for sex, to be quite honest, i never even think about it any more and could happily live without it for the rest of my life. I have enough in my life with my kids, my interests, my home and my extended family. Sex is something i dont miss, and i dont see that changing.
That might sound sad to a lot of you out there, but my life is so rich in many other ways, my dh and our problems is only a part of that and i am now taking steps to ensure that i put my own contentment and health and happiness first.
