Search Results: second chance checking

I went out with a co-worker of my brothers. We both had a great time (talking and laughing through the whole movie). A couple days later I ask her out again, she says yes, but tells me she'll have to let me know on the date.
A week goes by and still nothing, I text her but she didn't reply. She works at a petstore where I go weekly to get petfood and when I walk in there she walks up to me and when I ask her about it she tells me her phones not working. This goes on for a couple weeks, till one day I walk in and she's the only register open, as she's checking me out she's talking and making jokes, but I didn't reply or say anything but "thankyou" and I walked out. After that, I stopped going there.
A few months pass and I get a text from her saying "Hi, how are you?", she makes small talk and I finally ask her why she's texting me after all this time as if nothing happened. She explains that she had just got out of a bad relation ship when we went out and wasn't ready to date again, but responded to it in a childish way. She told me she was very sorry and didn't know what she was thinking at the time, I told her I forgive her and that was that. Eventually I star dating a girl who becomes my girlfriend, this only lasts for a few months. I ended up breaking up with her because of how flakey she was and time after time I gave her second chances, till I realized she was just doing it again. a few more months later I start going back to the pet store and I see the girl again, I had forgiven her so I felt no anger toward her. We would make small talk and that's all, I would see her maybe once a month. She started telling my brother she wants me to give her a second chance, but is afraid to ask me. My brother said she doesn't stop talking about me. I regret giving the chances I did to my ex, and that's why i'm reluctant to doing it again. I believe to find the one girl I'll spend my life with, and i don't think that a girl that reject me once is right for me.
