My friend is obsessed with her boyfriend?

One of my close friends is obsessed with her boyfriend. He lives across the country, but they met each other during a wedding (they're not blood related). Ever since then they've been texting, and messaging each other non-stop. She's not allowed to date so shes constantly hiding it from her parents. In the beginning, it was alright, it was kind of cute. After approx 5 months it really started to become annoying! Whenever my friends and I get together, the first person to talk will be her. Instead of saying hi or asking about us, she'll start off by saying "Guess what _____ did?!" and she'll tell us what he said to her, which is usually something really cheesy. The other thing is she'll show us what he texted her which is usually something really corny and not very cute anymore. Its the pretty much the SAME stuff everyday and it gets really, really annoying. Its not even just us who she'll tell, she'll pretty much tell every single one of her friends what he said on a daily basis and its annoying. Sometimes i think that all she really cares about is him. She says she "loves" him but we're only in high school O_o. She'll also keep track of how many days they've been together. A couple weeks ago she told us it was their "anniversary". I honestly didn't really care though. I told her that if I was in a relationship then I would never really care to remember how many days passed. She told me that if I really love the guy, then I'm gonna remember. I think thats bs and annoying. If he doesn't message her for 2 days, she'll start whining and get upset about it. She'll also start acting really "sexual" with him. She always tells me that he was 'being horny last night' and that he said gross things, which she also says too. So now I'm just confused as to whether I should stop being friends with her or if i should confront her about this...
