Here is some context for the meaning "leave one's husband" from James Clancy, A Treatise of the Rights, Duties and Liabilities of Husband and Wife: At Law and in Equity, Law Press, 1837. The excerpts below discuss the extent of the husband's financial liability for his wife when she has left him.
"But if the wife, instead of being turned out of doors by her husband, or being obliged to leave him in consequence of ill-treatment, elope from him, he will not be liable for necessaries furnished to her after the elopement.", p. 33
"And the mere elopement without any act of adultery will be sufficient to discharge the husband, as it was held by C. J. Raymond, who said that 'if a woman elopes from her husband, though she does not go away with an adulterer or in an adulterous manner, the tradesman trusts her at his peril, and the husband is not bound.' If, however, after such an elopement, the wife offer to return, his Lordship seems to have been inclined to think the husband's liability for necessaries would have been revived.", pp. 33-34
