Giving a fake apology
"I think the biggest mistake anyone can make when apologizing is not actually meaning it -- apologizing automatically or out of feeling obligated," says Tibbals. "The issue at hand, which may be a part of a wider problem, is actually not being addressed."
The phony sorry-to-end-the-argument apology is the exact opposite of what you should be doing when you’re trying to mend a problem. By essentially sweeping the argument under the rug with a half-hearted and over-accentuated "sorry," the problem gets buried in the angriest part of your brain, allowing it to resurface in the most inconvenient of times.
Not taking a breather
"Taking a moment to engage and think through an issue, understand what happened, and determine if you are in fact actually sorry is important. One way to fix this is to fight the impulse. If you feel yourself starting out a heated conversation with something like, 'Look, I'm sorry, but...' maybe take a beat."
