<human>: Can you condense the text into three sentences or less?

She was my best friend, I thought she was the one. But after some mistakes and a year of constantly making her cry, I can no longer live with this.

I love her, she loves me, but three times she said it would be best for us to end, and crying I begged her to stay. Yesterday she said it again, after only 2 days, and I just agreed.

She flipped. This time she begged me, and she said she's gonna change, and that she believes I can change. She is waiting for me to go celebrate our thirteenth month. It hurts so much, and I want to go back on my words, but the damage is done. I feel as if it will be a matter of time until she resents me for breaking her heart again. She already resents me for sleeping with another woman two weeks before I asked her to be my girlfriend.

I know I'm no saint, I know I ruined what could've been a beautiful relationship. I had plans for us together, and I gave my best effort to make up to her the disillusion.

But I'm tired of walking on egg shells.

It's hard for me to describe how beautiful many things between us were, but there's also the fact that we could hardly date without her getting mad at me.

I was her first time, her first love, and right now she doesn't accept is over. I don't know what to do, I'm afraid of this being a mistake, I'm afraid of breaking her too much. Please advise.
<bot>: I'm her first love and she doesn't accept it's over. I love her, but I don't think we'll overcome our problems.
