<human>: So this past August, I recently moved to a new city (Portland, OR) and have been off and on the dating scene since. By that, I mean some weeks I'll be content with being single and not really wanting a woman's affection and other weeks my MO going out is to meet a girl to hopefully start a relationship with (not just a hookup, an _actual_ relationship).  

Since then, I've met a total of 4 women that (based on my own opinions and observations) I felt a real connection with and had good times with on a first date. Thing is though, every single one of those women would suddenly "disappear" on me, and by that I mean they won't respond to texts or calls so any chances of a 2nd date are gone. I don't bother trying to contact them after a day; I don't want to be overbearing about it and if they actually cared, they would've contacted me back within a reasonable amount of time.  

I'm really confused about all of this and need some help explaining why this is happening. It can be one of the worst feelings in the world to have met someone and the two of you both enjoyed each other's company, only to never hear from them again for reasons that you'll probably never know. The first couple of times it happened, I didn't think too much about it. But the fact that it keeps happening gives me cause for concern.  

I consider myself a fairly attractive person and easy to get along with. I've been called a gentleman numerous times in the way I treat women with respect. I'm not socially awkward and I find it easy to make pleasant conversations. I keep up with good hygiene, keep a clean home, good health habits altogether (no smoking or drugs). But I feel that there's something about me that's warding away women after the first date and I honestly have no clue why. If anyone else has been down this road, any words of wisdom will truly be appreciated.  

Oh, and don't throw the "other fish in the sea" thing at me. It doesn't mean much if those fish don't want seconds.

Can you condense the text into a few key points?
<bot>: Despite really great first dates, I've been having bad luck getting 2nd dates to the point where they don't message/call back. Any clue to why this is happening?
