i lied a said my boyfriend choked me and now he in jail what can i do

You could file an affidavit of non-prosecution with the DA, but a lot of counties will still prosecute domestic violence cases anyway. Did your boyfriend do something other than choke you? Did you have any physical marks showing violence against you? You also must be careful what you say to the police and the DA because making a false police report is against the law. Women who are victims of domestic violence often take back their allegations once the perpetrator is arrested. If you have concerns about how to deal with what's going on, contact your local domestic violence shelter or go to www.thehotline.org
