People stay in horrible relationships way too long with the hopes of “working things out.” More often than not, things never work out! The time to get out of a verbally abusive relationship is NOW! In baseball there is a rule that after three strikes, you are out. And in some states across America there is a “three strikes” law.
Therefore, I believe as well in the “three-strike rule” when it comes to being verbally abused. The first time a person verbally abuses you, even though it's awful, can be written off to “having a bad day,” “not feeling well,” “having PMS,” or “testing you to see how far they can go”—pushing their limits with you.
The second time it happens is horrible, but it can be attributed to “a life crisis” (such as job problems, problems with children or with family members excluding you, health issues involving anything from a cold to impotence, menopause, or a life threatening illness). But the third time it happens, there are no more excuses. You're out! Leave!
