Have you considered you might be a psychopath?
You've just described many of the traits.
I don't necessarily believe in love either. There's definitely connections between humans which encourages empathy and loyalty and things like that, which is an adaptation for success. Love makes sense because tribes and kids are more likely to survive with loving parents and connects etc. Inset other scientific reasons here. So I think love is just a term for an emotional state where you feel connected to, loyalty to, compassion for etc. a person, to a degree where they become a priority, which when reciprocated, creates a more powerful unit. And then you can interpret that in a million ways and have different combos of feelings, but it's certainly not an actual emotion which is the same for everyone. It's an undefinable descriptor.
Crying is another cool adaptation I learnt about fairly recently actually. It's an act of submission. You don't really cry when you're facing danger or threat from strangers. You cry when either you know the perpetrator, or after the event when you're safe. It's debilitating, the eyes are blurred by tears, and it taps into other humans (with empathy) to show you need support. If they step up, you improve the connections mentioned above, in a mutual way. So while it is weakness, it's weakness which can result in a stronger unit. And humans have only succeeded because of their teamwork … so we cry for a reason.
As Arny said … "I know now why you cry. But it's something I could never do". Maybe that should be your motto?
