In one of the episodes in DS9, Quark's mother was reprimanded for speaking with a stranger. If a Ferengi woman is forbidden to speak with a stranger, how is she going to fall in love and marry given that a relationship has no chance to even start?
Falling in love and marrying was not considered typical for a Ferengi
From Memory Alpha:
Marriage, like everything else in Ferengi culture, was a business contract, signed between the prospective groom and the bride's father, in which the father leased his daughter to the groom for a set period (usually five years) for an agreed fee, paid on the birth of a son. (DS9: "Doctor Bashir, I Presume")
Therefore, we can see that a Ferengi female was not a party in the contract, but more like the subject of the contract.
And from Chakoteya, Quark talks to his brother Rom about his wife Prinadora, and Rom's and Prinadora's child, Nog:
ROM: I should have told her how I felt.
QUARK: Thank the Nagus that you didn't. Remember what happened with Nog's mother? Yeah, don't want to think about her, do you. Let me refresh your memory. You signed a standard five year marriage contract with Prinadora's father because you wanted to have a child. A simple everyday business deal. But then you fell in love with your wife and wanted to extend the contract. And you were so in love that you never bothered to read the extension before signing it. So in the end, her father swindled you out of all your money. Prinadora left you for a richer man and you got stuck with Nog. Hooray for romance.
ROM: Leeta is not Prinadora.
Emphasis mine. Quark states that the contract is standard, and that it is an everyday business deal. Therefore, we can assume that this description matches a typical Ferengi marriage arrangement.
I believe that the only female that fell in love and married because of love, is Quark's and Rom's mother, Ishka. As we know from the Deep Space 9, she stood against all anti-female regulations and laws in the Ferengi Alliance, up to the point that she was wearing clothes!
Edit: There is also a small talk between Quark and O'Brien about the results of such marriage policy on Ferenginar in DS9: Fascination. It seems (from Quark's perspective and as objective as Quark can be to prove his point) to work pretty well :)
O'BRIEN: What was I supposed to do? Force her [Keiko] to stay here with me?
QUARK: That would've been a good start. You humans, you never learn. You let your women go out in public, hold jobs, wear clothing, and you wonder why your marriages fall apart.
O'BRIEN: That's your solution, Quark, huh? Treat women like property?
QUARK: Criticise it all you want. But on the Ferengi homeworld, husbands and wives never argue. There's no divorce, no broken homes, nothing but peaceful conjugal bliss.
