Love of my life

My love of my life broke up with me little over 5 months ago and we still live together i want the relationship back but I need to work on my issues that led to the break up she says im in my head alot and I lied but I also am trying to figure how i can show her I have changed i am a very big codependent and im in coda for that I just want my life back with her and her children any advice cause my heart won' allow me to give up o know this could work. I often realize when I don't bring up the relationship it's smooth sailing and I get more communication from her.
