Yes and no; when someone falls in love, it is a subjective experience that should not be put under a single blanket term. What this claim entails is misleading, yet it can be true – or completely false – under different circumstances. Love has never been one cause equating to one effect.
To your credit, there are solid reasonings evidencing that emotional vulnerability can foster conditions where love can emerge or grow deep. As an example, psychological-built models of intimacy tend to emphasize that being vulnerable through self-disclosure is a key point in growing emotional connection. A position argued in this study claimed that “vulnerability must be under appetitive functional relations, consensual, and empowered for safe intimacy to emerge.”
Research on falling in love also puts forth the suggestion that certain states of lowered inhibition or higher levels of emotional arousal facilitate a stronger drive or depth for emotional attraction. Another example would include a study cited by Scientific American: that arousal and lowering reserved natures can accelerate the bonding experience between two people.
So, in the right context, yes, emotional vulnerability does seem to conform people more towards the ground for love.
However, the mere notion that every experience in regards to falling in love has to do with emotional vulnerability is misleading. For a fact, vulnerability is not always a safe way to interact with others. Being vulnerable does not guarantee you will find your soulmate, or someone to love. In many cases, it conducted a less healthy outcome. A study found that when your psychological state lowers into vulnerability, as it holds a low tolerance for stress, and a tendency to follow negative thought patterns; these thoughts followed emotional distress, which lowered relationship satisfaction within the earliest stages. Vulnerability when it comes to bonding can be a risk just as much as it is a healing process.
The same review shone light on the fact that vulnerability becomes functional for intimacy only when it is consensual. So long as it occurs in a safe relational context – lacking power dynamics, abusive tendencies, trauma resurfacing, emotional risk, or manipulative dynamics. Vulnerability can very well be exploited easily, which is why an attempt to romanticize it, by saying it leads to love all the time, is to deny those who were injured by it their validity.
