a girl at my college i like and wondering if she likes me.?

we talk frequently at the college cafe and other places in the building. i met her 2 months ago in college and sparked up something with her, but i don't know what. I know i like her, but don't know if she likes me. She seems like she likes to talk with me and seems interested in what i have to say;she's very open to me and wants me to be open with her. She sometimes puts her arm around me. she told me her last boyfriend was like me and she ask me to walk with her to talk some more. However, i become acward and nervous with her at times where i think she may feel acward. I aslo see her around other guys and i dont know if she flirting with them. she also told me she was wondering if was going to kiss this other guy in her corus class. that made me feel like she wasn't interested in me. I told her she's pretty and she told me that i wasn't bad myself. there were times when i was going to ask her out, but failed. she wants me to be open with her. do you think she likes me?
