Online Dating Blog

Salam,
i have this friend who talks to this girl online, they live in diffrent locations and they haven’t met yet.
my friend is a muslim but his gf/future wife is not. she’s a christian.
but she is a nice girl since everything that my friend has told her has been accepted by her.
for example he said when they meet they can’t huge or kiss or even touch eachother.
she said she respects that. although i would be sure that she would want to kiss him and hug him.
but she said it’s going to be really hard not to.
my friend said there is one way, if they get married, they can kiss and huge.
so the girl has accepted to marry him before meeting him (i think they want to do it over the phone or something).
so since the girl is a christian, my firend can marry her, and they’ve planed everything out.
they want to get married, and they’ve talked about it, although they’ve never dated eachother, so it’s been halal for them so far (AlhamduliAllah).
but the thing is when they talk, they tell each things like “i wana kiss you,” or things like that.
so is it haram to only type and say it to eachother, although they haven’t met, but they will probebly get married?
my friend is a good muslim or at least trys to be, and i’m kind of worried about what he’s doing.
is this right? or would you say it’s still haram?
peace.
