Please help me with this

She's certainly had a lot of male acquaintances since getting divorced. She has even made me meet several of the so-called "boyfriends". How many has she introduced to you/you to/for you/you for?

- Which one of: ...to you?/you to?/for you?/you for?

- Should it be single or double quotation marks around "boyfriends"?

- Should the period after boyfriends be inside or outside the quotation marks?

- And is the rest correct?

Thank you very much.
