There are definitely some things you shouldn’t say in an argument. I mean, I know that tempers are fraying and you are beyond mad, and probably quite hurt, but uttering some words can make the fight seem so much worse. If you aren’t careful, a heated argument can become an all-out war, and maybe even the end of a great relationship. Keep your wits about you, though, and avoid these things you shouldn't say in an argument.
1. It’s over
This has to be one of the top things you shouldn’t say in an argument. However hurt and upset you are, keep things like this to yourself unless you actually mean it. The same goes for declaring that you are moving out, or that you want a divorce. Unless it’s actually happening, and you are completely sure, don’t say it.
