A few women have said hi to me ... but fail to say much more ... I used to write my heart out now I am saying much less... Is more better or just an aloof comment what do women like?

If someone just sends a "hi" and you reply in any form or fashion, it's more than likely their next message is going to ask you for personal contact information to go off-site.

Use your big head not your little one.

Time and attention

?????????

I usually give back just a little more than they give. But the point of finding the right one is to find someone matches with you, so if you like to write then go for it. If they do not like to read all that then they are not right for you...easy test.

And admiration. Basically an ego boost.

What I want is a meaningful message, something that makes clear a man is truly interested in me.
It has to be and feel genuine, not some default message.
If there hasn't been any contact prior I do not appreciate lengthy messages.
It's rather presumptuous as well since you don't know yet if the interest is mutual.
It's the same as telling a stranger in the supermarket your life story. You wouldn't do that either.

And if a woman sends you "hi", I'd seriously question dealing with a scammer.
I doubt a real woman with real interest would send "hi" and nothing more.
You could reply with a short message that does show interest/has an opening so you can see what comes from it.
But personally I feel a woman would send more than just "hi".

Nailed it ;-)
