I don't know if men get this too (guy readers, lemme know if you do), but women often get the advice to give a man a chance if he's a bit boring. The logic is that a healthy, secure man might not trigger the stress feelings related to 'that spark', and so if he's boring, it's actually a good sign.
But every best friend I've had (guy or girl), I've known, often in the first 5 minutes of knowing them, that we were gonna hit it off. And these people are still my friends up to 20 years later; they are healthy people, they show up, they're loving and communicative and available and genuine.
We had that spark big time, from the first conversation. I never, once, thought these people were boring.
So why would I apply that framework to dating?
