I've been in the zone myself while dating but never bother to ask why because

...it doesn't really change the outcome so instead of wasting time, I just move on to the next target as there are plenty of fish in the sea  :

I think I have my life together. So why do I always get 'friend-zoned'?

I try to attract a partner, but I’m always told, “You’re so nice, I don’t want to ruin our friendship.”

I own a few cars, I run a music store and I play live music frequently. I’d like to think I have it together, and that that would be attractive. But there's been no prospect for romance since college — until recently. I met a woman who seemed amazing. She was in my city to get her PhD and we played music together. But I feared she’d look for greener pastures — and she did. Off she went after graduating.

Despite my accomplishment s, my love life is always lacking. I’m trying, but it’s hard when every time I seek out love, the world just strikes back. How do I keep putting myself out there?

The reality of body chemistry and physiology, is a primal nature.  The behavior of women, sometimes acts out that she needs to be conquered.  She needs to be challenged.  She needs to be won over like an object, a trophy, before she submits.  Not for everyone. 

You get friendzoned because you will be second choice or lower tier.  You have already been conquered by her, no challenge, nothing to be worked on for her to control and reinvent by her whims.  Nice guys do finished last if they ever do. 

There are basically two typed of archetype.  Family oriented or not.  Flip of the coin and it's fifty fifty, but seems like it's always the wrong side sometimes.  If the man is family oriented, seen as fatherly, protective, brotherly, said to be friendly as a friend and she is not family oriented, seen as motherly, nuturing, healing, sisterly, then the chemistry is wrong.  Even if the dating chemistry seemed great.

Because not family oriented people will always be adventurous, thrill seekers, rebellious, risk taker, places to see, places to be, people to talk to, etc.,...makes for great dating chemistry at first.  But they will never settled down.  The conversation should never be, let's start a family and even lead to lets get married.  The conversation and relationship with such people will always be, what are planning to do, where are you going, what's your next goal or adventure in life.   They may elude to such typical answers like, starting a family, settling down, etc.,... to mirror the goals of typical family oriented archetypes but then they will always choose other social events that is not family oriented.  You gone to a club party and met someone, good luck with that unless thats both your lifestyle choices.

Is she going to cook a home meal for a date or does she want to be taken out for fine dining?
Does she choose make up with bold flashy style or does she choose simple tone down?
Does she have homemaking skills or lacking?

Some people are just looking for adventure partners for life.  Some are just looking for a comfortable easy vacation for life.  Some are just looking for primal satisfaction partners.  Dating chemistry does not equate to lifestyle chemistry.
