Well done OP.
However hard you imagine being with someone with children, multiple it by 10 and you are still not there.
For every lucky woman who writes that they are happy, there are dozens who would not do it again.
They invariably end up as unpaid, unappreciated skivvy aupairs, working full-time!
Funny how many of these BMD ( bare minimum dads) end up with solvent, house owning single women with good jobs.
They know EXACTLY what they want in a new partner. A woman to house and pay for half of their children.
Often they will have a child with the new woman to lock her down.
Then suddenly the woman has a baby but she spends her life doing everything and paying for all his children.
Half the time the men have absolutely no interest in the new baby, it was purely a means to an end.
The less foolish ones get out with their child, but many remain, full of regret.
Stick to your guns.
I have two daughters and the above is what I would tell them.
Avoid. Better to be single anyday than to end up as a skivvy aupair to some lazy selfish loser.
The step parenting forum is full of such stories.
