A "Friend" is inviting me to a party on saturday; do you think i should go?

OK, so i used to have a good friend. unfortunately, i accidentally told an embarassing secret about her to a couple of kids. After truthfully apologizing to this friend, our relationship grew cold. She proceeded to ditch me in front of everyone and act like she was ten feet tall. Eventually, I went up to her and we cleared things up. She said that she did hold a grudge and she apologized. . but im still a little scared of being friends with her again because she lies and makes up stories sometimes.

Anyways, one day, i had to take a huge step so everybody i knew would come up and congratulate me for this event. my "friend" came over and congragulated me. She came back again and invited me to go over her house with a group of other friends. She said: "we need to start hanging out more because i want it to be the way it was before". What was weird was that i, being 15 years old, was invited to go to a party full of 18 year olds. So, i don t know about that. Anyways, do you think i should go?
