How do Girls aloud feel abut Cheryl's new single?

I was wondering about how the rest of girls aloud might feel about cheryl releasing a new single and album with out them cause if it was me i would feel like she was a right backstabber because i think it was really mean to just leave them and she also putting pressure on them to also do amazing things and look up to her really cant stand her but what do you all think???esspecially as nadine does pratically all the singing so she is kinda use them
