The people who "come hardest out the gate" are usually going to be unhealthy and unhealthily attached or discard as soon as they get bored, ironically. Male or female.
Also, losing interest rapidly, or devaluing a person rapidly. Someone said to me recently there are two types of people, (cliche but whatever)
Those who meet someone, anyone, a friend, lover, a business associate, and instantly thinks they are great, and loves everything about them, and then very quickly is disillusioned and starts tearing them apart in their mind, bit by bit.
and those who mostly withhold a lot of judgement, and bit by bit build that person up realistically, until they have a solid foundation based in reality.
One easy example, one of my boys, was infamous for the former, that's how every single one of his relationships of ANY kind went.
