There is a cliché question that many women ask all over the internet and in the real world: "Where are all the good guys at??" or "Are there anymore good guys left?". The simple answer is YES, however it's not as simple as finding him. If it was, then there would be much less complaining about it.
What exactly constitutes a good guy?
This has to be asked first. There really isn't a definition that encompasses all good guys in the world. For one person a good guy is one that works 40 hours a week, goes to church, volunteers at the animal shelter, and doesn't do drugs. For another person, it's a guy that has amazing hobbies, spends time with his mom, and is in the military. You ask 100 women what they think a good guy is, there's a good chance you will get 100 separate answers. So perhaps your idea of a good guy is very specific which makes it much harder to find this unicorn.
You aren't attracted to the majority of them
Good guys come in all types of shapes and sizes. Some are Asian, White, Black, or Latino. Some are short while some are tall. Some are obese while others are shredded. Odds are you are interested in a certain type, which will significantly reduce the chances of finding a good guy that you are attracted to. The good guys that are attractive are a smaller population than average or ugly good guys....and this takes me to the next point
The most attractive good men are in extremely high demand
A man that is 6'3, makes six figures, is 10/10 in looks, isn't a womanizer, graduated with honors, lives in his own home, and on top of that is a quality good man will essentially make him the most desirable amongst women. You will have competition from the best women. Unless you stand out somehow, odds are you probably won't stand a chance.
You aren't looking in the right places
How exactly are you finding guys to go out with? Are you going to the local hole in the wall bar, or using tinder? These might not be the best places to find that good guy. Good guys are everywhere, but they don't just magically appear. There are tons of good, nice men who aren't manipulative fake nice guys that are simply overlooked for various reasons.
My advice on how to find the good guy
My best advice is to at least give guys you might not normally pay attention to a shot. It won't hurt to talk or get coffee. Maybe he's not 6 foot, but he's still taller than you. Perhaps he doesn't have the best job, but he is financially stable and has amazing cooking skills. Maybe he's not totally in shape, but you could be the one who inspires him to be a marathon runner. The point is that waiting for something perfect is unlikely, instead find someone who you have amazing chemistry with and you'll be shocked at how the other things become unimportant.
