I’m more inclined to agree with @Coloma on this. It may not be a factor so much of how open you are to cause men (I’m presuming) to open up to you like this as much as a description of a certain pathology in you to be attracted to men (or to attract men) who use this particular tactic.
Because it’s one thing to be candid and frank in our dealings with one another, to be open to experience and communication – and love, yes, certainly. But it is another whole kettle of fish to dramatically and tearfully “unburden” oneself on a relative stranger… and probably, to be blunt about it, as part of the type of dating and mating strategy that @Darth_Algar has described. Because some men sometimes use that ploy.
But if that’s the particular kind of man that you’re drawn to yourself, or the kind that you tend to attract – which might be even worse, because it’s more difficult for you to avoid attracting such shallow men, whereas if you determine that you have a defect or fault, then it’s something that you can own up to and work on – then that’s not a happy scenario. Because let’s face it, men who act in this way are not deep thinkers, calm, reflective and placid (as a rule), and they certainly aren’t the “strong, silent type” (unless that’s also just another affectation that they assume for purposes of bedding another type of woman). They’re players, trying to play you.
If that’s your “type”, then heaven help you. Seriously.
