I'd say to be a parent of children qualifies as life and death job. A mistake or bad upbringing can damage a person for life especially if it happens during childhood. Not something to be taken up as a challenge like any challenges we may face in our careers. It's not the same. Failures may cost a life.
Most people enter these situations with good intentions. But they don't realize the difficulties of jurisdiction and limitations imposed by others. There will be things you can't do or say and discussions required on discipline. If they reside with the other parent it's a three strand chord and hopefully they're cooperative.
In a perfect world everyone gets along. But oftentimes that isn't the case. If the parent is absent that's another issue. And you have to scrutinize their upbringing. Are the parents permissive or orderly? You won't be able to change things without a struggle.
Financial considerations can't be ignored. If the marriage goes forward you're legally obligated to support them if they're minors. The ex is legally entitled to seek or amend a judgment for support in light of the union with periodic increases. If the parent loses a job the judgment remains. It may be adjusted due to reductions in income but they won't throw it out.
The ex can make your life miserable and poison the child against the new person and the parent. In most instances the new person bears the brunt of it. They become the scapegoat. If it's a widow that's a different story. There's usually less drama.
In some respects I feel it's a calling of sorts and you need to be in prayer throughout. A few of my associates adopted children. They had several of their own and the Lord led them to do so. I think that's equally so in these situations. It's not enough to like someone there's innocents involved and their needs can't be ignored.
My best friend in high school went through this. Her mother married a man with three young children and the ex was a nightmare. She sat us down and had candid discussions and showed us the paperwork from court. She warned us about the realities of those connections and unforeseen events. We were young women (16) and nearing the point of adulthood.
I've had similar conversations over the years. Sometimes they listen sometimes they don't. And maturity doesn't make everything kosher. Adult children can be something else. Pushback on later marriages isn't uncommon. They're trying to protect their investment. It sounds crass but oftentimes they're afraid she'll get everything. Because men have done that and the children take her to court.
That's the reality of our culture. It may differ elsewhere. The courts usually side with the woman. When you hear men complain about financial injustices and supporting her lifestyle they're telling the truth. Judgments can be garnished.
