I know it's popular to talk about "high quality men" etc when one is dating, but to be frank the whole thing is an anathema to me, and seems horribly objectifying.
I don't believe there are people who are objectively good, or objectively bad, to be in a relationship with. I believe it's a two sided thing, and about finding a good match for you.
I have had four long term relationships (two of them marriages) prior to this one. So I don't exactly look like a "high quality woman". However, I believe I bring loads of good qualities to a relationship - faithful, high earner, intelligent, kind and caring, relatively pretty, etc.
Obviously I have my trickier aspects as well - I am argumentative, impulsive and easily bored, and (most seriously) have struggled with addiction issues previously tho sober now.... My exes weren't perfect either. My previously relationships broke up because of issues between the both of us, not because I was perfect and they were deeply flawed, or vice versa ....
OP, the men left on the "dating market" now probably aren't perfect. But that's because there are no perfect men. Are you perfect?
It's possible to find someone who is perfect FOR YOU, or at least close to it. I am now with somebody who shares the same scars so that helps, and he is also clever, kind, loyal etc so it's a good match. He has MANY failed relationships in the past, but they weren't with me, were they? It's been quite a few years now and we are working well so far.....
It depends what you are looking for really. If you expect somebody to be the complete package you will never be happy. If you want to meet somebody flawed (because they are human) but lovely to you, who will augment your life, it just might work! Good luck.
