I actually think this is on her. She might have minor inklings of wanting to be married or pay lip service to it, but at this age there is no way she is going to humble herself for the men that WOULD acknowledge her b/c she would be taking a risk on a man broker than her who could STILL cheat or betray her AND try for alimony if they don't make what she makes.
She legitimately has no incentive at this point to look to lower tiers of guys for marriage, and it's unlikely that one of the richer ones will meet her requirements of faithfulness, attractiveness, and wealth. I could see her paying the white tax.
