I think PucePanther is getting an unduly hard time here.
Its nice to see a bit of balance about what single parent hood can be like. Everyone's situation is different. Not every mother who becomes a single parent will be able to support her family, or spend time with her kids as she is working so hard, or suddenly be happy and carefree when she is worn down by the worry of poverty, or have a support network of family and friends. Or have the money to date or childcare to form a new relationship, or indeed to socialise at all. Not all kids will be happy in their new situation. You see posts here quite commonly from utterly worn out single parents.
Some mothers are happier after a split. But each woman's situation is different, she will know what her situation will be like upon splitting, financially, socially, mentally. She will know what resources she will or won't have to make a new life. She will know the disposition and situation of her kids and the impact a split will have on them (not just the split but the other life changes following it). She will then have to judge how bad the current situation is and whether the move will lead to an improved situation for her / her kids and then have to balance this to make a choice.
I don't think it is fair to lambast a poster for talking about her experience and how it affected her, just because it wasn't other people's experience. She has a legitimate point of view, as do those for whom a split was the best thing.
I agree with this, having seen both sides of it. Each situation is different, and much also depends on whether it is handled in the best way for the children rather than what suits the adults.
My parents were not well matched and married too young. However, they made little effort to save their marriage. Then, upon divorcing, we were moved to a different region, to new schools, and it did severe damage to us all. Our parents were toxic about each other after the acrimonious split, and both remarried people who were completely unsuitable as step parents. As a result, our childhoods were traumatic and we were much worse off in every way.
My own husband cheated and left us when my children were babies. He also said he "never loved me". As PP have said it's important to explore what you mean by love. For him it meant the excitement of new relationships, so he skips from one to the next to the next. That is not love.
Separation has worked out fine for me, after the initial aftermath and emotional hurt. My children are happy and secure, they have a lovely home in a better area than previously as I've secured two payrises since then. They were also young enough to know no different: although it was extremely hard for me single parenting with such young children, the emotional impact of divorce is usually much worse for older children as their whole world is thrown upside down.
I am actually happier now than I've been in many years but if separating had involved children moving away from their friends or school, or not being financially secure, that might be a different story.
What strikes me from a large number of the comments on here is how much of it is focussed on finding a new man. I have absolutely no desire to do that, I don't need or want one. We are happy. And moving in a "step parent" is a risk I would simply never take with my children, it is not fair on them to have to live with someone else, and in cases like my own childhood it is physically dangerous.
Separate and start a new relationship if you must but put your children's needs first as they had no choice in this. Let them have a home with just you and them. Ensure an amicable relationship with your ex (which in your place OP should be easy from what you've said. Mine had behaved appallingly so it was hard to do this but it had to be a priority for the children). And plan how to find happiness and build a different life on your own. This idea that parents need to jump into a relationship with someone else to be happy is a source of many of the problems that arise for children following divorce, IMO.
