Is the wife considered coerced into breaking her fast in Ramadan due to her husband forcing her to have intercourse and to eat and drink, and what is the expiation for her sin, and how does she know that Allah has accepted her repentance?

If the reality of the matter is as you have stated, then you have broken your fast willingly to your husband, and you must repent and make up the days. Expiation is obligatory upon you according to the majority of scholars, while some believe it is obligatory only upon the husband, and this is the preferred view on our website.

Your husband must repent from intentionally breaking the fast in Ramadan, having intercourse during menstruation, and ordering you to break your fast, as these are grave sins indicating his audacity and transgression of Allah's limits. If your husband does not repent and insists on doing so, there is no good for you in remaining with him. You are permitted to seek a divorce due to harm, and it may even be incumbent upon you to separate from him if he does not desist from this reprehensible act.

As for the acceptance of repentance, that is from the Unseen. However, the servant is commanded to repent with its conditions: ceasing the sin, regretting it, and resolving not to return to it. If these conditions are met, it is hoped that Allah will accept your repentance.
