Feelings can't bruise you or injure you, and you should not feel guilty for keeping yourself safe. It's not selfish, it's smart.

We often tell ourselves it's not that bad, we deserved some of it, we started the argument, we burned the dinner, we spent too much money, we woke up late, we can justify just about anything.

Pretend a friend of yours was in the same situation. What would you say to her? Would you let your friend take the blame? Would you tell your friend "stop being selfish, go back to that man, don't make him suffer" or would you say "come crash at my place while you figure things out."
