3 years together, she wants marriage and I don’t. Is this the end of the relationship?

tl;dr 40M with higher income/assets dating 35F (with a child) for 3 years. She wants marriage; I don’t. Concerned about California divorce risk and prenup enforceability. Decide between marrying with financial risk or ending the relationship over incompatible goals.

Me, 40M, $1M net worth, $300k income, no kids

Her, 35F, $500k net worth, ~$150k income, has a kid

We both don’t want to have a kid together

We have been dating for 3 years

She is pressuring me to get married

In California, prenup leads to a 70/30 split plus reduced alimony, anything less and the judge throws the prenup out to 50/50 split and full alimony

Also in California, divorce can drag out until you are both broke

Option 1 - Get Married with Prenup, risk losing 30% to 100% of my assets

Option 2 - Tell her I’m never going to marry anyone, risk losing her
