Wow. I think my Ah left out only one excuse on that list.
Wonder what a 20 excuses co-dependants make list would look like?!
Here's a few from the top of my head (Oh what I wouldn't give for a gender free, acceptable pronoun!):
1. He/she can't manage without me.
2. If I love them enough they'll change.
3. I
must be making a mountain out of a molehill.
4. We're soul mates and I must do (endure) anything for love!
5. He/she needs me!
6. He/she's not as bad as the stereotypical alcoholic.
7. He/she's special.
8. Divorce is bad.
9. I'm staying for the kids.
10. I'm not perfect either. Until I am, I should focus on my own flaws and not theirs.
Feel free to add...
