I agree about the piousness.
What I don't get is this.
Any woman who asks for advice about ending a relationship becuase she isn't happy in it any more but is worried about upsetting the kids if they split will be told almost unanimously that she should leave her DH, the kids will be fine, it's better that than stay in an unhappy relationship, what kind of role model are you showing them etc etc.
But when anybody wants to leave a relationship and also be with somebody else, the reaction is often well that's terrible, how can you take the kids away from their daddy, you will screw them up for life, don't do it, it's selfish etc.
Relationships for life are rare these days. Most people will split from a long term partner at least once. It's just a fact of life, and if handled sensitively etc the kids should come out unscathed.
Of course OP should be single for a while first but she has met this guy now, and has a relationship with him.
It just isn't as cut and dried as many have suggested.
