I encountered the same thing with my ex. He made more than I did but we still split all the bills while married. That was his decision and so when it came time to talk about divorce, he would tell me that I wouldn’t survive on my own with my earnings. I don’t know much about the legal aspect but I know from others that you are entitled to half of all assets. Luckily, we agreed on everything. Not sure this response is helpful but hopefully you can agree to things and make it an easy process.
