When I was single, I didn't give a dayum if a woman told me she loved me everyday, she wasn't getting it from me, unless I absolutely felt that way. Period!!!
I don't care if it's a week, month, year, 2 years, love has no timetable, and your friend needs to understand that, and if that's what she wants, and can't get, she needs to get to steppin.
GUD, I can understand being in a friends corner, but getting yourself emotionally caught up in their relationships can be mentally draining for you. Tell your friend to schit, or get off the pot.
Right now it seems as though you're taking it just as personal as your friend is (not saying that you are), and if you are, you're in their bid'ness just a tad bit too much, and it may be time for you to give your friend your advice, and then back up off that relationship. You've said what you can say, and done all you could do, and now it's up to them....but as aapw, and others have said, love has no timetable my friend, and ones actions will tell you more how they feel, than any word can say.
Good luck with your friend.
NICE
