Praise be to Allaah.
Talaaq and zihaar (kinds of divorce) are the hands of the
husband, not the wife. But if the wife declares her husband to be haraam
for her, that is an oath (yameen), so if the oath is broken she has to
offer expiation for breaking an oath. The oath is broken if he has
intercourse with her.
This has been discussed previously in the answer to question
Based on that, if what you meant when you said, The limit of
Allah is between us, was to make your husband haraam for you, then when the
oath was broken you have to offer expiation for breaking an oath, which is
to free a slave or to feed ten poor persons or to clothe them. The one who
is not able to do any of these has to fast for three days.
But if you did not intend to make your husband haraam for
you, then you do not have to do anything.
And Allah knows best.
