My husband has a teaching degree. He has quit or been fired from 5 teaching jobs in 2 years. Can he get alimony from me if he refuses to work?

My husband and I are not yet legally separated but we are physically separate. We have decided to legally separate. He has quit or been fired from 5 teaching jobs over the last 2 years. He just lost his 5th job. He is insisting that he will take the next 3 months to go on sabbatical and expects me to pay all of our mutual bills and send him $1000 a month for his housing and expenses. I have been consistently employed for the last 10 years. I have a small inheritance from my father. I just sent my husband $4500 to help him get on his feet. I used my inheritance money for this. Also, he took a sabbatical after losing his 4th job and I sent him over $4000 to cover his expenses then, and I paid all of our bills during that period of time. Now he wants more money from me and is threatening to sue for alimony. He is capable of working but refuses to get another job doing anything this year and expects me to cover all of his separate and our mutual expenses. Does he have a leg to stand on?
