Oh, jesus, why do I do this?
I'm going to elaborate.
If you're just having fun, then all that hard to get stuff is fine.
Here's what I've noticed about it long-term though. and this is both as a person who often played hard to get (kind of unintentionally) and someone who was once on the receiving end of such treatment.
The person playing hard to get is orchestrating anxiety in the pursuer-- "Do I like you? Are you good enough for me? Keep chasing and we'll find out!"
But what happens when the chased decides to turn around and say, "Hey, you've proven yourself, I like you, let's try this." ????
Again, in my experience, one of three things:
1) the chaser is like, oh shit, I just like chasing. Now I don't know what to do. I think I'll go find someone else I can pursue because the chase is the fun part for me.
2) the chaser is like, thank god, the anxiety is over, I was so sick of chasing, let's try this- but then the chased realizes that the day to day relationship stuff is rather boring and/or realizes that it was their partner's anxiety that felt like "love" to them. So the only way to feel "loved" is to try to keep their partner anxious, which, while it can be prolonged, (usually by threatening to break up intermittently) will also make the chaser into a shadow of their former selves-it's not so exciting being loved by an anxious wreck.
or 3) I guess it could work out long-term? I mean, I've never seen that happen with people who've made a career of chasing or being cased, but I'm sure it works sometimes.
So basically if you want something that's going to work long-term, try to avoid partners who insist on chasing or being chased, and try to avoid being the kind of person who only likes chasing or being chased. And then focus on 1) being the best most interesting person you can be and 2) genuinely adding value to your partner's life so they won't want to leave you because you're really just that awesome--- not because you're super adept at playing games and inspiring anxiety.
I've seen a lot of people on the internet peddling this idea that, "Women LIKE feeling lovesick, they like the anxiety, that's why you have to keep them on their toes," but shockingly, I've noticed the same thing about men--- their interest flourishes when they're not sure if they've "got" me. So would they like being kept in a heightened state of anxiety long-term? Probably not. I'd be interested to see if someone who sees the opposite sex through this lens has actually managed to build a long-term, supportive, mutually satisfying relationship with a mentally healthy individual.
But I guess it does depend on what your goals are.
