Should i continue texting a guy who's broke my friend's life? 10 points !!?

my close friend, mandy, has been dating adrian for 8 months. adrian has been a total jerk to mandy, acting un-gentleman and treating mandy like dirt. everyone hates adrian now coz mandy's so nice and we dont want her to date someone like adrian. but mandy loves adrian so much, even though she duzent really like the way he's treating her. not long after, they broke up because their parents didnt agree. then adrian realized how stupid he was to treat her like that, and now its over. a month after they broke up adrian started texting me coz he's bored. and he needs sum1 to talk to. he really misses mandy, so i helped him and mandy. but then mandy's besties started to get mad at me for even replying adrian's texts coz adrian's such a jerk and stuff. and mandy keeps on telling people that im so lucky to be texting him. but then adrian keeps on texting me, but i dont want mandy to be jealous, im helping her, and i dont want her friends to be mad either, adrians been a jerk but hes changed.
