its attractive to some guys but many guys these days are lazy and they go for the easier chicks. my sis is elusive too and the guys she was interested in, who were also interested in her at one point, gave up very easily.
It may be interesting to the wrong kind of guys who simply want to chase someone. I would much rather a girl I can feel comfortable with than one whom is hard to communicate with because they think being hard to get is a good thing. I see it as they have something to hide and if that is the case they can keep it.
In my opinion, elusive and mysterious women are not appealing. Its not about the secrets or the shyness...the issue for me personally is when I finally get a mysterious girl to open up more to me, I find that she is...boring. I feel like I just wasted my time, and her time. That is not to say that all women that are "mysteriously elusive" are boring. It's just the ones I had met in the past. I would rather have a woman that is more open and that expresses themselves more, especially in something productive because I can relate to her somehow. I cannot ever relate to someone that is going to be elusive.
They're appealing for like the first month, then it just gets annoying as hell. Sure it's like "Hmm...I'd like to get to know her more" but then you realize you're not going to, then it's just like "Wow this is getting old..."
I've been told the same thing, and I've had similar experiences. I think it makes us seem interesting and challenging which attracts guys, but from past relationships it's become a problem when I'm not very transparent (even when I think I am!). So from my experience that vibe attracts guys, but it frustrates them when they try to get to know a girl who doesn't open up quickly. Just my two cents!
A guy told me once that I'm like a book that he always wants to read the next chapter because he never knows what's coming for him so...For many its is appealing and especially the ones that want to take you seriously and not just out what´s behind the elusive person...
