@Elixir86 I haven't really been "dating" so to speak, ever. All my relationships (haven't been a lot, been together with my wife since university) have been organically grown, lol, like some accidentally dropped tomato seed that ended up bearing fruit. So, I can only consider what I see first-hand from people around me, friends, family, people at work, focussing on our age group (based on the number at the end of your username, you and I are the same age).
So, the way I see it, it never, not once is it worth drawing conclusions and generalisations, ever. By that I mean, is that we are all so very different individuals, so there is no point taking what you learned about one person and have that influence how you will look at the next one. I have seen this so many times happen - for simplicity's sake, I will take an extreme example: A lot of women I know get fed up, and with one brush stroke conclude that they are sick of men, they are all clumsy, they all want one thing only, or that they are cheaters, liars, etc, to name a few. Now, I do not suggest that you are giving off this vibe, at all. Just using it as an example. So, just because Joe, John and Tom treated you badly, does not mean Jim will, too. But even if Jim treats so bad, does not mean Mike will, too. (treating you bad, being bad communicators, tricking you, or being crappy in bed, whatever it is...) I could go on, but no matter how many men we queue up, one thing is constant: it will never ever mean that their flaws or mistakes have anything to do with someone who might come your way after them. So my main advice would be to try and avoid conclusions, maybe forget about types? Do not get me wrong, it is healthy to have preferences, we all do :) I do not mean objective truths...It is a 100% good to outline things you couldn't be on board with, so that is not what I am trying to get at. My point is to not think too much about boxing them or analysing people's motives retrospectively, because at the end of the day, you will never know 100%, they are the only ones who do. For example, your last guy - whether he was genuine in the beginning, meant well, then changed his mind for whatever reason, got cold feet, felt insecure about sex, ended up not vibing with your pheromones on a chemical level, or had someone else in mind he would rather be with, randomly decided to be on his own, or heck, out of the blue decided to disappear from our modern society and become a monk in Tibet, matters very little.
I would try to look at it from this point of view - yes it sucks that it went nowhere, it sucks that the promise of a potential good thing was there, BUT, isn't it a lot better to have it end in the earlier stages rather than getting more serious, investing even more time only to fall flat in that stage, years wasted?
I would just say, be yourself, stick to what is important to you, and you might bump into someone who will want exactly the same things from life as you... Or shares most of them, making new ones together,...And who knows, even be a more compatible sex partner for you. Anything is possible.
