hm........... well if she seems comfortable to talk to you then let her.... did you say here b/f know about it or knows the cousin?
all i can say is that she's old enough to make up her mind to do something about it if she wants to take some action..........maybe she's not the only one that its happened too , but couldnt make it stick...........
when it happened to me......... i was molestered when i was 5 by my teenage cousin.............. well.............. my mum talked to his mum who naturally denied it........... so nothing was done considering i was 5......... we ended up moving away .. along way away.......... i have never been close to that side of the family . ever again..........


the thing is......... this guy..... her cousin. is a creep. he could have any s.t.d's she really need to get to a Dr if she already hasnt.......

the thing with anything like this is that you can get an "over emotional attachment" to someone - anyone ( a sexual relationship , to fill a void )
or go the opposite............. I didnt have a sexual relationship until i was 21 - i had lots of guy friends (i guess when they're your friends they ARE NOT your boyfriends)

as far as your holiday .............. maybe invite her......... get her away from everything and everyone............ let her sort her self out............. but let her do her own thing............ dont be her crutch!

certainly you need some r& r too

but the family should know
the b/f should know too............ maybe he'll sort this guy out for her.......... but either way she need his support........... which she's been getting from you

hope this helps
