Make no friendship with an angry man; and with a furious man thou shalt not go.
Get to know your boyfriend really well, young sister, before you accept his hand in marriage. An angry, violent boyfriend will become an angry, violent husband. And you will probably get the brunt of his anger. Again, anger like this has a cause and that cause needs to be found and dealt with. It’s best to do that before marriage. After marriage you will just become another abused wife.
