In the sentence "I love you in every lifetime," the word "lifetime" refers to the span of someone's life. It implies a belief or idea that there are multiple lives or existences, such as through reincarnation or alternate realities.
While it conveys a sense of eternal and unconditional love, it is not exactly equivalent to "I love you forever." Here's the difference:
* "I love you forever" means love lasting endlessly throughout time.
* "I love you in every lifetime" adds a poetic or romantic idea of loving someone in all possible lives or existences, making it feel deeper or more mystical.
Both express profound love, but the latter has a more imaginative and timeless nuance.
