I discovered that my husband has cheated on me multiple times. Despite my loyalty, I am struggling to forgive him and it is affecting my ability to care for my three children leading to frustration. What can I do to cope with this situation?
Bismihi ta'āla
You have every right to be upset, and every right to be frustrated, but you must control yourself, to make sure you do not fall short of your motherhood and parenting duties. Your children have no guilt in this, so they need your full attention and grace.
A promiscuous husband does definitely affect you as a wife, and you must put a stop to this. Discuss this with him, his family, your family, elders in the community, and if he continues his ways, you might need to make the strong decision of leaving him, if it is affecting you.
And Allah knows best
