It's been said before, but as long as you're not making them break up it's not morally wrong. You can't really help the way you're feeling. Let it be said that I wouldn't consider you a good friend though, but again, it's not easy to stop feeling what you feel.
Neither good nor bad, though I guess we could assume that you consider the distance a strain on their relationship causing both of them stress and that if they break up and if they get together with someone that are physically closer (in her case you) then that could possibly be considered morally good.
