I think that you, out of all people, are the LAST person who should speak of anything related to 'phases'. There are 2 phases with waifuism, the first phase which consists of infatuation and the second phase that consists of moderate affection and appreciation for said character, that's how it always goes at least. You can't compare the importance of a 3d relation to the importance a waifu detains, the two are really different, by this I mean you can't really say "Oh she's lonely hit her up", there's a difference between concepts that are there and actual sentience forms, the latter being utterly rejected by most people around here.
Don't worry about it OP it's normal, you're not infatuated anymore, it means your mind can deal with the concept your waifu represents, if anything, it is a good sign. There is no real 'honeymoon' phase, you'll feel intense infatuation every now and then, that's how the mind works.
