My boyfriends best friend just moved to town,should I worry?
his friend is big into the party life and drugs.
Well, you should only be worried if your boyfriend is getting involved in these activities with him.
if you trust him then no
The boyfriend is responsible for his own actions. If he's a responsible person, he won't get involved in those things. If he does get involved, then your worrying wouldn't have done any good anyways.
This might be a good thing , you might just find out how much he cares about you .
Then dont talk to him?
