Should I be in my friend's quinceanera?

Ok so I've been friends with friend A since like 6th grade and I've been in school with her like since kindergarden. She is gonna turn 15 in October and she invited me to be in her quinceanera. I'ved had my ups and downs with hers, she was my best friend for 2 years now and well I have had problems with her before but we get along well and make up. She gets jealous, mad you know, like every friend and well I don't know If I should be in her quinceanera. I asked my dad and he said it's up to me and he said that I have to remember all those times of jealousy and the problems I have had with my friend before. What do you think? 0:
