Your 'instant 'Aw Hell Naw! I'm out!'s' are what I would consider 'deal breakers.'
Your 'warning signs' are similar to 'rather nots' by my way of looking at things.
I also think, especially when it comes to a lifelong commitment, a person should be allowed their preferences, petty though they may seem to others.
Fifty years is a long time to sit across the table from someone who has annoying eating habits. It's a lot of basketball seasons when everything has to revolve around the game. It's a long time to have little in common to talk about. It's a lot of dirty dishes and socks to pick up and wash. Or to not have a dog because your partner doesn't like them. Or to have sex with someone you no longer find attractive because of their poor health choices or poor hygiene.
I'm probably a pessimist, but there is truth, IMO to:
Keep your eyes wide open before marriage, and half shut afterwards. -- Benjamin Franklin
