-Completely opposite views on travel (like oil and water).
I find that this is usually a very big deal. Someone really likes to travel, and the other person does not. Big red flag here.
-Will likely never agree on religion.
This is also a big red flag.
-Fairly argumentative (I am used to sweet women who are more laid back).
This could indicate a bunch of emotional or mental problems. She could have had an abusive past, or she may have a mental illness like depression. Untreated, it's a deal breaker usually. I.e. big red flag again.
I see 3 major red flags. I don't see this lasting.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
