저기요 guys,I need advice.

I have a friend who's 17 and has a boyfriend who's 28.In your opinion is this ok?And there's more.I suspect,I mean I'm almost sure that he's taking advantage of her.His age itself makes me think that,but it's not just that.Some time 이전 we were sitting together in the morning and she was talking on her cell with someone and said that that morning she woke up 의해 cigarette smell because her boyfriend was smoking.I was really shocked when I heard that,but I didn't say anything and I tried to come up with an other logical explanation.Also 더 많이 recently we were talking with an other friend of ours about girls' hygiene stuff and she told me that 다음 년 when I get 17 "you will become a woman" so I'll have to be 더 많이 careful with my hygiene.Well,I'm 16 so she couldn't be talking about period.If she meant sex when I get 17 I'd rather kill myself (her tone of voice also suggested quite much certainty).And since she's 17 and "becoming a woman" means what I think she "has become a woman" 의해 that pervert?!Again I didn't ask her if that was what she meant and tried to come up with an other logical explanation,but I've yet to find one.She must have been with him at least for a couple of years because she told me once that one summer she'd gone with him and her 프렌즈 close to the place where I spend my summer holidays.I didn't 코멘트 neither about spending her holidays with her boyfriend(especially this one) nor the thoughtlessness of her parents for letting her. Yesterday in the morning we were at school with the other girl we hang out with and she told us happily that it was her boyfriend's 28th birthday and for 1 sec I was like "OMG!" before I utter a stupid birthday wish.I already knew he's older because she'd told me that he owned a shop,but I hoped not that older.I haven't expressed my opinion and suspicions to her neither for his age nor for the things I mentioned above.I never said anything because I didn't want her to be mad at me,but do 당신 think I should?But,guys b
