"I do not have a boyfriend."

Translation: Nie mam chłopaka.

Nie mam chlopaka does not mean i don't have a boy. It means i don't have a BOYFRIEND!

"Nie mam faceta"? I was told by a Polish teacher that this is acceptable

[Jellei]

Well, that's colloquial, and colloquial wording is a bit of a slippery ground, we rather don't accept colloquialisms. But yes, that's a very basic one, it generally means "guy" and in such a sentence it does mean "I don't have a boyfriend/husband/partner".

The difference between chlopca and chlopaka

[Jellei]

They are Accusative form of "chłopiec" and "chłopak". They both mean "boy" ("chłopiec" is younger, "chłopak" is older, up to a young adult), but only "chłopak" means "boyfriend".
