Can you still date her after she lied?

This girl n I like eachother for about 2 months now. Been hanging out every day. She pays for me to do lots of stuff with her and same with her family. Her family really likes me and told her not to mess up and lose me. Well, the last 3 days I've noticed she's been texting this girl a lot. Her and this girl almost dated awhile back. I confronted her and she lied to me. Well, my friend was told by the other girl that the girl I liked said she liked her still. So I confronted her again and she denyed it then finally admitted it. She obviously was mad I busted her. She said we're not in a relationship so why does it matter? I said cuz you lied. She also said well wouldn't u of rather have a friend tell u i liked her then me? I laughed at her immaturity. She came over later that night and we talked. She couldn't stop crying and she knows she messed up. She likes me way more then the other girl and cannot help liking someone else she says.. Also said she didn't wanna tell me cuz she knew she'd hurt me. I was like idc if you like someone else just don't lie to me. What do I do here? I'm not sure.. I want to give her another chance but then again idk if I should.. I need some mature advice please. Thank you
