A hookup is just a relationship, HOPE. It could be a relationship that is short-term but it is a relationship irrespective.
And, yes, a short-term hookup can develop into a long-lasting relationship, HOPE, not if you are treating your hookups like shit (simply because they’re just hookups!) and never if you are ready to allow the people you hook up with treat you want shit (since you’re merely a hookup). Treat your hookups like individuals you may in fact see again—like people with peoples emotions, perhaps maybe not simply peoples holes and/or poles—and you may in fact see them once again.
You may also end up in a relationship that is long-term.
Now, sometimes people hook up with strangers exactly they don’t know and don’t expect to see again because they wanna have sex with someone. And that is not at all times an idea that is bad sex with an individual who that you do not be prepared to see once again can be extremely liberating.
