<human>: Could you distill the essence of the text into 1-3 sentences?

[Sorry if my English isn't perfect]

I have 2 close friends who both I have known for about 7 years. About 3 years ago they happened to end up in the same university in Australia, and have been good friends since then. In the past year, he got a crush on her but he didn't do anything about it. He's never had a girlfriend before and is really shy and awkward when it comes to girls. Anyway, on Valentine's Day, he manned up and sent her a big nice looking bouquet of roses (which surprised everyone) which afterwards she posts on Facebook and Instagram. They've been on 1 date ever since, and they've been texting a lot. The guy tells me that he is definitely sure that she's into him.

He wants to make it official by doing something, but he hesitates because this can potentially become a long distance relationship, which he is fine with. They were in the same university but he was one year ahead and just graduated, so she still has 1 year left, and she's leaving on the 25th. What should he do? If he wants to pop the question of "do you want to be my girlfriend" or something like that, where and how should he do it? Remember that he is kinda shy, and I did tell him to be himself.

I also am forbidden from talking to the female friend, because, in his words, "Don't ruin this". So I don't know her side of the story.
<bot>: Male friend wants to start a relationship with another friend of mine, but will turn into long distance if succeeds. She's into him as well, but neither is making a move. What should he do to make it official?
