bringing your side chick to couple's therapy

[Ostap]

"Although Russia did continue bombing Ukrainian cities the whole time that the peace talks were happening, which is not a good sign. I mean, bombing a country during your peace talks, is like bringing your side chick to couple's therapy."

Does he mean bringing your side chick instead of your wife, or together with your wife? Usually I would expect the former version, but given the context I didn't exclude the latter option.

upd: I should've watched a couple seconds later into the video first, there is a joke that makes it clear it's the latter option.

Together with your wife.

It would show a total insincerity, which I think is the intended meaning.
