ex girlfriend who i left wants me back

OK I was seeing this girl for a few years before i finally told her to f,o ... because i didn't feel i could trust her , i took her from a boyfriend she was with for 5 years .... recently i went back to her after a few years and we started seeing eachother but she had another boyfriend of 4 years she was with i was trying to make her my girlfriend again and she was sleeping over regularly i told her i felt bad about doing this to her current bf and i don't think i could just see her i wanted to date im pretty sure she told her b.f to get lost because i went to there house a few times and slept in there bed after a while we started to drift apart i figured she went back to the guy, one day she tells me that we could never have a normal relationship so i was kinda immature about it i deleted her out of my phone and my fb ... a week goes by and the police kick in my door and charge me with a lot a different charges and I'm going to jail for a good few years as I'm sitting in jail i cant stop thinking about her a week goes by and i make bail and I'm waiting to be sentenced the day i get out of jail on bail she re adds me on fb and tells me that the day this happened she couldn't sleep and that shes really worried about me and wants me to stay in touch with her , i say well you left me why do you even care and all she will say is because i do ! so i get her number again and tell her ill call her every so often while im locked up ....

I don't know what she wants tho really i just wanna fark her before i go back to jail or have congical visits with her , but our conversations on fb are short and seem awkward .... do you think i have chances to Get Her Back or do you think she just feels sorry for me how do i get her back if you guys think there is a chance
