the best piece of advice i've ever given:

Thats a really sticky situation, i wouldn't go for him honestly babe. hes left you 3 times and now he's telling you that he loves you? it hardly makes any sense. if he truly loved you then he wouldn't have told you because he knew it would make you're life so much more dramatic. and plus since it was sarahs first time, it would kind of be like a devistation to her having her best friend date him. i know this sounsds corny but if you love him, you'll let him go. and you'll find some way to get over it and find out a way to find love again, but it is you're choice, just listen to what you're heart says. what i just said was an oppinion and something i think, its all up to you, adn thasts one of the hardest things, i know you want someone to tell you what to do, but it's best it came from you.
