<human>: I lied to my girlfriend in the past year about smoking weed. I didn't think it was a big of a deal at first but she really didn't like it. 

One time she got really upset when she found out I had lied to her. And I ended up throwing out my equipment and did everything I could to try to win her trust back. Everything was fine for a few months and we were really happy together.

Last week I smoked again and lied to her about it and she ended up finding out about it. I told her I never did anything on Wednesday. I gave in and told her because it was eating me up inside to keep this lie. She get very upset and told me to leave her alone. I have hardly been able to sleep or even eat. She basically ended things today and I'm absolutely heartbroken.

Is there anything I can do to win her trust back? I love her so much and she means the world to me. I know I messed up and I wouldn't be here if I hadn't realized that and realized what I lost.
