Are you rich? Will money always flow freely to your child? Children cost an incredibly amount of money.
Quality extra-curricular activities are expensive. I spend about $2k per kid per year (violin, gym, theater, etc).
Private school, if your child needs it, is expensive. It could run you $40K per child per year.
Even if you go public, summer camps are expensive. $200 a week minimum during most of the summer.
Tutoring for test prep, academic evaluations, therapies are expensive (the latter most often not covered by insurance). One evaluation I 'm looking at for my oldest with will cost me between $3K-6K.
Everything that as a parent one can do to get one's child ahead of the pack to succeed is expensive.
And then what about a minimum of outfits and accessories so that your child doesn't feel left out socially? Those trendy clothes and electronics add up too fast for my liking
So... you really need child support.
Even if your spouse doesn't have a dime to his name right now, he might later on and be made to pay it.
Right now you are depressed with low self-esteem and can't think straight. Hire a good lawyer to help you. Don't be afraid to ask people for help and stop thinking about disturbing their comfort. They're not the ones going through a divorce right now, you are! Be insistent yet polite.
You will really regret it later if you don't fight the good fight now.
