Right now, children is sort of theoretical for you. That's fine, as it's like that for everybody. Once you have them and have fallen in love with them, you'll find that their happiness is worth working things out with their mother, rather than breaking up. If you can't man up enough to put up with her shit (assuming there is any) and you do break up, the money will be going to your kids, who you'll love, and giving t…
I make a quarter million dollars. No, that money certainly won't be going to my kids. It's utterly ridiculous to pay that amount of money for child support for one child.

There has been a meme for a couple decades now, that kids are so expensive and will cost millions of dollars to raise, etc. This meme is doubtless responsible for much of the reduced birthrate.
You can spend as much or as little as you desire on kids. I grew up shopping at Goodwill, but now I buy $40 shoes that my kids will wear for 6 months before outgrowing. That's my choice, as there are cheaper new shoes and much cheaper used shoes. Somebody else might buy their kids $120 shoes and complain to their friends how expensive their kids are. It's a shame that people like to promote this myth of the expense of kids.
If you can get over your trust issue with your GF, her not needing to give up a high paying job and being able to be home with the kids is a win. She won't feel like she's missing out on something and your kids get a much better childhood.
