This entire thread is nonsense since no one has ever come back to tell us what it’s like in Shamayim concerning spousal relationships. No one is taking a stroll together or having a picnic in Shamayim; it’s an entirely different dimension of which we have no concept of.
Same thing goes for T’chiyas Hameisim. The g’mara may speculate on some issues, but we don’t know how it will conform to our existence today.
Moshiach is another story, nothing will change except that the goyim will recognize that Hashem is the true one and everything that results from this belief; and we’ll have a lot of answers to our questions.
