Listen to one of your podcast , I got the impression there would be no man that could live up to your expectations, "I'd rather be single at 40 then marry the wrong man" - "and I love being single" - in your 30's (the old you get the harder that becomes) at a point you get set in your ways and to have someone come into your life and turn that world upside down can be difficult ,and the excuse "I can't find Mr right" is deflection i believe to staying single - you can think you have all your ducks in a row and you can think your with Mr right person in dating/courtship ( let's face it dating and to some extent courtship is a illusion much like porn it's not reality.) marriage is still a roll of the dice no matter how careful you are, some of best intentions and you can still end up in a horrible marriage, people change and not always for the better . sometimes it takes a leap of faith!
haha, a guy breaks up with you, and you thoughts are "maybe he wasn't good for me"? Where's the accountability? He broke up with you because you were not good enough. Change and self improve, do better.
