Kleonike

On page 24 I notice that when lysistrata asked for the other women’s support to end the war (before telling them that the way was to abstain from sex) Kleonike responds with 

“you can count on me! If you need money, I’ll pawn the shift off my back ---Aside and drink up the cash before the sun goes down.”

I never really got this, Kleonike throughout the play seems to be a close friend of lysistrata and one of the main women holding the strike in place, yet here she is pledging her support, only to then seem to be very shady and not supportive at all. I mean, she says, I’ll do everything I can to give you money, but then use it all right away instead. I just want to know everyone’s thoughts on this, so hopefully I can understand it better.
