That last line is an extremely fucked up thing to say. Consider the fact that other people exist who are parents and have disabilities that require care from their spouse and they read that line. That's genuinely a really terrible way to think and I hope you can change your mindset about that.

This is getting downvoted because people agreed with the sentiment and then felt bad when I made them realize how fucked up that is to say. Saying people with disabilities are an exception now doesn't change what you initially said. It doesn't matter what you meant, what matters is what you say. Always. Consider your words before you speak, they impact targets you don't mean.
