You are Sun in the 11th house of your friends.
Your friend is Merc, both ruler of and domiciled in the 11th house of friends.
I think you will remain friends, in a large part, due to your devotion to the friendship as show by you/Sun [as well as her] being in the house of your friends. But the friendship has really been put to a test for her with you. As strong as her interest is in friendship with you, as show by Merc in its dignity, she is in detriment both by retrogradation but also by moving into combustion with the Sun/you.
Combustion with the Sun is very debilitating for a planet. So I see tough times ahead for the friendship where you can consider all you can do cultivate and nourish it again. I think that is the key to reestablishing it, once your friend has gotten over the upset, the fullness of which she has yet to feel.
Moon's next aspect is to Saturn, so there may be some obstacles.
