Lior,
Halacha has no concept of the secular-style ongoing alimony other than the one-time kesuba payment.
You are essentially correct, and I may have mistakenly made a spurious analogy. Whereas alimony continues after a civil divorce is finalized, in halacha there is the payment of the kesuba, after which the husband has finalized things. One exception is if the ex-wife is nursing his child; he is obligated to pay her the wages of a nurse maid through 24 months. He is also obligated to pay for his kids’ needs through age 6 when the mother has custody.
My alimony reference was directed at a husbands obligations in certain circumstances before a get is given.
His obligation to support his wife while married does not obligate him to support her out of his home if she decides to separate,
I didn’t say “if she decides to separate”, I said, “in many cases where the couple R”L separates.” Separations don’t just happen when the wife walks out.
and his support obligation is fulfilled by stocking his fridge with food and the closet with clothes and inviting her to live in his home to utilize that support.
Not necessarily.
If he forces her out of the home then that obligation of his would continue wherever she is.
Can you clarify this statement? Do you mean him stocking his own fridges and closets?
His rights to her earnings can only be ended by her agreeing to waive his obligation to support her.
That is almost exactly what I said, except sometimes these waivers are enacted by a Beis Din due to unfortunate circumstances.
