Should I ask her out again?

[agreeablewren371]

This girl and I at school really hit it off a few months ago, things were great, she thinks I'm very funny and I sometimes stop by her work to say hi, She always responds to my messages even at 1am. I decided to ask her out on a date, she said yes and things were good, things started getting awkward, and I felt like she wanted to tell me something. I ask her if she is still good to go out, and she says yeah!, I'm gonna see my boyfriend first. I brush it off and cut her off immediately, and I don't text her the day we were supposed to go out to eat. I'm walking to my locker and I see her looking at me with her head rested on her locker arms crossed staring at me,(the day she told me she had a boyfriend) she looked upset, or not happy I guess. I still text her not to look like a total jerk, and she tells me her relationship is over. We haven't spoken in person for over 2 months. We recently started talking again, and she seems pretty happy about, it when she walks by we smile at each other. She followed me on instagram (don't know if it matter). We talk but its almost like we are strangers, like meeting a new person. Also I just moved to the school so I'm pretty new. Should I ask her out again? how should I go about it.
