Are you good with advise? Click here!?

I have been hanging around this girl for 2 months almost everyday. I could tell she liked someone else n busted her lying to me saying she didn't. She didn't tell me cuz she likes me more n didn't wanna ruin what we have. By her lying I felt she's already ruined something that could've been good. I decided to give her another chance. My friends, everyone knows she likes me a crap ton. She admitted to the other person in front of my face that she likes me more. Ok, is it a good idea I give her another chance? I guess she was very down n upset around her other friends cuz i had stopped talking to her for a few days. Suggestions?
