Search Results: falling for best friend

This one girl and I became friends a while ago. I invited her to a road trip.
We went next state over and she invited her "best friend" to meet up with us in that state.
Anyways, things escalated at the end due to dehydration and tiredness ( I drove the whole 8 hours) and got a little cranky. Just wanted to sleep and I'm driving around everyone. She ditched me and left with her best friend. I told her I didn't like that and cut her off. She went to another friend of mine and told my friend I've been talking about her. So I had two people attack me that same night. I blocked her from everything.

Fast forward 6months later -- she messaged me through a phone app apologizing. I don't know how she got my number. I unblocked her number and texted her. She said she was a horrible friend and she was sorry. I met up with her because I'm a pushover. She stated she didn't want to be friends with me again but she just wanted to check up on me. Then she kept inviting me to come to her birthday party. I said no -- I don't feel comfortable doing that. She kept pushing me to come ( I didn't end up going either) She kept saying she didn't tell anyone about our falling out-- however when she shows me on social media this girl asks her why she's talking to me again. She keeps hanging out with this specific girl as well. Every time she says something she just lies and I catch it but don't say anything. I believe in keeping my enemies close but I don't know I don't consider her as a friend.. just someone to hangout with. I have two other friends who do not like this girl at all. They keep telling me to block her and they just don't vibe with her whatsoever. But I'm too nice. What should I do? Am I being too nice? Would you tolerate someone like this? We met through mutual people and haven't been friends long either.
