<human>: Can you give me a shortened version of the text?

I have been with my girlfriend for about a year and 3 months now and i don't know how much longer that will last. I'm in love with this girl but I've done terrible things to her. 

long story short is that I'm jealous and possessive and i did not realize that this was wrong until recently she called me with the intentions to leave me. i tried molding her into something that i liked and had a problem with her talking to guys or wearing certain things out etc. 

she lied our entire relationship saying that she didn't want to talk to boys or do these things that i made seem not okay. i was mentally abusive. I realize now that i put my girl through abuse and I'm repulsed by myself and saying sorry will never be enough. we talked about it and i know what is wrong with me and i know what i have to do and shes giving me a second chance but the only thing is is that she has put up a very thick and tall wall and i don't know what to do. 

i know that a lot of you probably have no sympathy for me and i don't blame you but if you guys could give me some advice on the matter that would be very much appreciated. Thank you
