Ladies I need your advice on this one?

Okay, my woman left me for her ex. Said she always had feelings for him. I was heartbroken but now I'm over it. She didn't want me to call her or text her. Which I won't anymore. I believe she still loves me, because as much as I was getting on her nerves she STILL didn't want to hurt my feelings or say anything mean to me in frustration of me calling her. However, I know it sounds crazy but I will always have love for her. Even though I told her to not call me when things go down hill with her old flame ex. Truth is, I still want to be with her even after the way I was done wrong. Love is always forgiven if you ask me. Anyway, I want to ask her to Marry me. Should I wait until after she's broke up with this guy or ask her now? If now, I look desperate, If later, she'll be vulnerable. It's really hard to decide when? I want this woman for my wife. I don't care about now. I will win in the end. Help me out? Ask her now or later? I'm thinking a year later. She's just infatuated with him.
