Her husband promised that he would divorce her after her period ended
Question

                A problem happened between my husband and I. He beats me for every small and big matter. So I went to my neighbour and refused returning to him. He said to me: “return to your home for one month, until you get purified of your menstruation period then I will divorce you”. 

I returned for this reason, but later he said that he does not intend to divorce me and that he said what he said only to let me know the Islamic ruling on divorce; that it should be after one menstruation period if he does not have an intercourse with me.  I refuse what he says because he promised me and gave me a word when I was at the neighbour’s house, that he will divorce me after the period. Is this considered divorce or not?.
Praise be to Allah.
    If a man says to his wife: “Go back to your house and 
    children for a month, until your period comes then after it ends I will 
    divorce you,” this does not count as a divorce (talaaq), because it is only 
    a promise of divorce. Divorce does not take place unless the husband 
    actually issues a divorce after the period. 

    A person may decide to divorce, then change his mind, and 
    perhaps that is better for you and your children. 

    It is essential that the relationship between the spouses be 
    based on kindness. It is not permissible for the husband to beat his wife 
    except in the case of her being wilfully defiant (nushooz) and not 
    responding to his exhortations and advice or forsaking her in bed. But he 
    does not have the right to beat her on her face or beat her in a way that 
    causes severe pain. Allaah says (interpretation of the meaning): 

    “Men are the protectors and maintainers of women, because 
    Allaah has made one of them to excel the other, and because they spend (to 
    support them) from their means. Therefore the righteous women are devoutly 
    obedient (to Allaah and to their husbands), and guard in the husband’s 
    absence what Allaah orders them to guard (e.g. their chastity and their 
    husband’s property). As to those women on whose part you see ill‑conduct, 
    admonish them (first), (next) refuse to share their beds, (and last) beat 
    them (lightly, if it is useful); but if they return to obedience, seek not 
    against them means (of annoyance). Surely, Allaah is Ever Most High, Most 
    Great”

    [al-Nisa’ 4:34]. 

    We ask Allaah to set your affairs straight. 

    And Allaah knows best.
