First of all: You have the right to choose who you want to date, and why. So the only questions I would ask, and have you answer for yourself, at the very least... are/or might be -- Do you feel you were rash in your decision making? Was it based on / or rooted in impulse. For instance, you say that, "(Your) My feelings had huge fluctuations..." And that he had a great sense of humor, seemed to get along w/him fine-enough to warrant good friendship status. However, it feels that in the romance department, that then is where his insufficiencies lied. And so, if that is your primary reason for dropping him. Then that is all you need. And probably good enough. If you don't want to wait for him to learn, or wish for him to catch up, etc. Then that is fine and more than your prerogative. I would only ask yourself if you feel this was a justifiable reason given the totality of all else that was stated, and then calculate upon. In the moment, or at that time (while on vacation) you'd seemed to have decided that it was. Fine & fair enough. However, I'm just wondering, and not stating as if it were fact, whether or not you truly gave it a fair shake, and a chance to germinate or grow. If however, you knew, and/or know, just like right there & like that. In that instant in other words: "hey! There's no chemistry here - & that's all there is to it. I feel nothing for him, or this man, and likely/probably never will (no matter what he does, etc. moving forward & in the future. I just can't see it for myself, and that is that). Try to figure these things out for yourself, and in your own head. Then go about deciding how you would or would not wish to proceed. Keep things as (they) are, give him another or a second chance (just to confirm you were correct w/your initial observations & interpretations - your gut feelings & instinct; or intuition). As it just sounds a little slightly unwavering to me. But maybe I am reading it wrong. Or maybe you are looking for decent counters to your now current claim to help reinforce them, in order to not have to go through a second trial & error phase, or process like that of this experiment, as it could be made out to (otherwise) be. Hope you're happy! That's all that matters to me. : ) Truly, & take care~
