abruptly left an extremely violent and abuzive 10-year relationship
In 1997, I abruptly left an extremely violent and abusive 10-year relationship. My children were 14, 11, 8, and 6. Because I had such a large family, there was no room for us at any of the shelters. Therefore, for 6 months, my children and I slept at a different home every night. To insureour safety, I had to quit my job where I worked for 14 years. We were living on my social security income that I was receiving from my late husband, who was the father of my first two children.
I assume "abruptly" means "suddenly" and "abusive" means "rude in this context, but still I could not understand the emboldened parts even though I know the meaning of individual words.
