That's idealizing and it's not healthy for a long-term relationship. Sooner or later (probably sooner) one has to be faced with the fact that the human you are bonding with is, well, human. And as such - flawed in so many ways, as all humans are. If you can admit that, really be honest about it, and still value the relationship and your partner, because there are so many things beyond the flaws that make it work - then it has a future. If it's just blind infatuation that ignores the reality - it's a fling, and the reality will assert itself soon. Nothing wrong with an occasional fling on certain stage of one's life, but it is good to make the distinction between the two.
