Anger Issues
When you’re in love, there are some bad qualities that you can and will overlook. Just make sure that an uncontrollable temper isn’t one of those things. The OP’s mom had a friend who was all set to marry this “great guy.” There was only one problem – when he got mad, he turned into the Hulk.
Although the OP’s mom advised her to leave before it was too late, the friend genuinely thought or at least hoped that he would change. She quickly realized that this wasn’t the case when they got into a bad argument a day before the wedding and he flung a table past her head. Nothing gives you renewed perspective like almost dying. She canceled the wedding and never spoke to him again.
