In hindsight this is true. Hitler also threw up loads of red flags, and yet the only senior person in the British G'ment who didn't trust him was Churchill. Everyone else (not just Chamberlain) failed to see the red flags and believed that he wanted peace.
If you like Audio books, get "Talking to Strangers" by Malcolm Gladwell, a really brilliant listen, and helps explain how Josh got pulled in so easily.
Many of us have been there at some stage - dating the wrong woman/man.
I have my own tale to tell. About three years after my divorce, and being on the rebound/heartbroken from the rejection of a work colleague who I had fallen for, I hooked up with a bird who was a friend of a friend (the first friend is no longer my friend). Anyway, I was lonely and she was nice to me, and seemed ok. Anyway, me being the reasonable passive guy that i am, i never really noticed that over the next few weeks, she basically moved herself in without me even knowing much about her. But when i realised what was happened I convinced myself it wasn't a big deal. It was nice to have someone around and the dog seemed to like her. But then the cracks started to appears. She had her own small business (freelance), but rarely seemed to be getting work. She convinced me the market was tough at the time. I was making ok money, so didn't mind paying when we went out. But then, I started picking up on a few lies here and there, like where she had been, her background, some money that went missing etc. Then the arguments started.
Anyway, fast forward, I caught her out in big lie (won't go into detail). and decided to end it, and chuck her out. Of course she begged, had nowhere to go etc. Eventually, I was able to be rid of her, but not until after she's turn up at my work and make a scene, had driven away my mates etc. Even six months after we broke up, she got drunk at new years and basically sent a whole bunch of accusations that i'd hot her etc. Luckily all of my friends saw through it, and some went out of their way to tell her to fuck off.
The whole scene from go to woe was less than a year, but it taught me so many lessons in life. I blame her for being a lying bitch who took advantage of me, but I also will be the first to acknowledge I ignored every warning sign as well. In this case, I don;t think it was my penis doing the talking, but my heart, which was vulnerable and she saw an opening.
This was seven years ago, and since then i moved cities, met Mrs CD, started my own business and a family. And my mates came back to admit they were worried about me but couldn't work out what the hell i was doing. Any thankfully nobody gives a hit about who I am... then again, I would also never live my life through Instagram.....but I urge everyone out there to stay safe!
