If you give advice to someone & then they get mad at you , What do you do ?

My friend Erin She was having boy problem & She was crying ALOT ! So i was texting her & Trying to get her calm , Cause i don't like seeing her like that . So the next day she's back with her boyfriend which i didn't want her to be . & She starts ignoring me the whole day . After like 3 days , She blocks me of her facebook & Erased me from her contacts & ooVoo & Stuff like that . I try to reach out to her & fix stuff but she doesn't reply back or NOTHING ! What should i do ? Cause i don't wanna close that friendship
