Ex blocked me on everything and this is the second time she has dumped me. hope?

I have made a different thread on reconciliation. But this is a breif over view for those who don’t want to read full story.
•I became insecure / took her granted/ became unattractive
•this lead to her breaking up with me
• i pleaded begged etc
•used nc worked on my self and got her back
• we were more in love that before
• month later we start arguing well me over stupid things
• i over react over small things
• started dealing with family problems which i didnt tell her about and took it out on her
• made her unhappy took her for granted again and pushed her away which lead to break up 2
• i became more insecure went on her facebook accused her of cheating when she didn’t
• next day i apologise she said she forgives me
• she deletes and blocks me on every social media site

Do i have any chance at all. Alot of people say move on but i didnt come here to get that answer even though it could be the inevitable i know that. I know i need to work on my self before even attempting to try to contact her
But when i do fix my self which i know a 100% i will cause i am capable of anything I set my mind to. What do i do then? How do i approach to contact her? We’ve been going out for just over a year. We got back together 2weeks before anniversary. How do i win the girl i have so much respect and love for back. I know i don’t need her. I want her. She was my best friend and my lover. I got insecure and trust went out the window. Romance died which lead to no intimacy and now no girl. I know she’s hurt. Any advice is appreciated. Thanks.

By starting this new thread, it shows you’re still obsessing. You received some good advice on the other thread, but you’re thinking ahead to how to approach her, when you really need to focus on making changes to yourself!
