You've adamantly written that you like your life as it is -- that band gigs are something you really enjoy -- which entails out of town, random events, that are an important part of your life -- and that you "can't/don't want to change" that.
Your life is thus, not conducive to meeting and then getting to know a woman in a natural, slower-paced way -- and you've stated that you're happy with this lifestyle and unwilling to change it -- which is absolutely fine and your prerogative.
Life is all about choices and consequences. And your lifestyle choices seem to have led to making it virtually impossible, to establish a real relationship with a woman.
My larger point was b/c of your lifestyle -- that you take any friendliness as an indication of interest -- and often make the leap to thinking a relationship has begun...when it hasn't.
You seem the type of guy, who meets a woman in a long line at motor vehicle or the grocery store -- and engages in friendly chit chat while waiting to check out -- and you think her friendliness indicates she's interested in you. And b/c of that -- you would then probably offer to help her to her car and load the groceries -- and get her number or go instantly into asking for a date.
For most people the friendly encounter is just that -- a brief conversation with a nice, friendly complete stranger. End of story. It happens every day to people.
You seem to take ANY encounter -- if the woman is friendly -- as her showing interest in you.
Only you can decide •what• must change IF you truly want a different result -- b/c clearly what you've been doing is not giving you the result you want.
