All of the sentiments you have expressed about how u r with people is how I am too. I came a cropper with this when I was much younger. This is how daft I was when I was around 27 and living in a squat. I came across a homeless man. In those days I was full of gods love, just how I was. I took him home and gave him a bed for a night. He then thieved off everyone. I should have been more aware, much more and seen the person, but I was t. But I still choose to be the same way, a lot wiser now of course. I have a basic trust in people until they show me different and I often give them 3 or 4 chances. I do, however, avoid manipulative people. I can spot them a mile off. A lot of air time is given to how gambling addicts re manipulative. I cam quite honestly say that in my gambling I was never manipulative with others. I never sought to hide it and I never borrowed from family or friends to gamble. We are all different people who have this addiction.
And there is nothing wrong with you. To trust people is a positive good thing, until they show you different. And on the f a f front, there is a lot of protection given on this site to f and f, more so than the gambling addicts. I have read a lot of f and f threads recently and some of what they go through is truly humbling pointing out how dreadful this addiction can be to spouses and kids. Luckily all mine had fled the nest before it all started.
I don’t think you are on the spectrum or that you lack anything. You are you and who you are is pretty ok in my book.
