Big time fight

Okay, so yesterday i had this huge fight with one of my friends because a few weeks ago i broke up with my boyfriend (we had a fight too, stupid fight), and she told me not to go back with him because good guys dont let a little fight end with their relationship... so i listened to her advice, but i did what i thought was the best... we're together again, he said sorry and everything is okay... but she got really mad at me and told me i wasnt strong enough to let go because i was afraid of being alone... Okay i think this is too much for just a fight with MY boyfriend, am i right? i mean she's a good friend, but its my life anyway... what do you guys think?
