What is oh i love it and i hate it at the same time?

This phrase generally expresses ambivalence towards something. It suggests that while there are aspects of the thing that are enjoyable or desirable, there are also aspects of it that are frustrating, disappointing, or undesirable. This can apply to a wide range of experiences, including relationships, work, food, hobbies, etc. It is possible to simultaneously appreciate and dislike something, and this can create conflicting emotions that may be difficult to reconcile.
