How do women in polygamy cope?

From a female CFB reader

"I have been married for seven years and I have always lived separately from my husband. He is in d military and works in Abuja while I'm a banker working in Lagos. My husband just informed me he is taking a second wife and there is no going back. I requested for a divorce, he refused saying he still loves me. We have 3 kids and are practicing Muslims. Please how do women in polygamy handle it because I am so traumatized just thinking about sharing my husband with another woman.
