Is Forgiveness Accepted

BS"D Hello, honored Rabbi, I am very troubled and not at ease, and I urgently need an answer. Last Saturday, we were guests at my mother-in-law's house, and I had a fight with my husband. As a result, I stayed in the room and did not come out until the end of Shabbat (from the end of the afternoon meal). My husband did not try to reconcile with me. At the end of Shabbat, I asked my husband to bring me something to eat and drink. He said, "If you want, go up to the house (we were staying in a separate unit) and take food and drink." I was very hurt and sent a message to my mother-in-law saying that I was very hurt, hadn't eaten since the afternoon, and found it hard to forgive. Something along those lines. And I did not go to say goodbye. Now it's important to note that my father-in-law is an important rabbi, and my mother-in-law is a God-fearing woman. And since several times I wanted them to intervene in our marital peace, and except for one time when they intervened, they were not willing to intervene anymore because they are the parents. Last Friday morning, I called my mother-in-law to ask for forgiveness, but there was no answer. I sent a message asking for forgiveness, but there was no response, and even before Shabbat began, there was no response until now. My husband knows that I asked for forgiveness. The relationship is already very complicated and on the verge of divorce, I am under mental stress, and I don't know what to do to make her forgive. I understood from my husband that his father, the rabbi, said that my mother-in-law is hurt. Please, I need good advice. Apologies for the sensitivity of the matter, if it is possible to ask Rabbi Fried directly, it would ease my mind. Thank you.

Answer from our teacher, the Gaon, Rabbi Avraham Frish, shlita:

You have done enough to ask for forgiveness, you do not need to do more than that.
