My question involves criminal law for the state of: Illinois I was arrested for domestic battery. My girlfriend who odes not live with me got into an argument in my house and she called 911 and said i wouldn't allow her to leave. The cops came and i was arrested she told the cops that i never hit her that she hit me i said the same she also said she did not want to press charges but i was still arrested. I spent the night in jail and bailed out in the morning for 200 dollars. I have never been arrested in my life i have no priors or a record

question 1 can i be arrested if she said she didn't want me arrested nor wanted to press charges
question 2 Me and a girlfriend are still together and on good terms and she said she is not going to court can i still be charged with domestic batter if she does not testify
question 3 does she have to go to court can she be forced to
