Your story reminds me a lot of an article I read about a South Korean film director who was kidnapped by the previous North Korean regime whilst on holiday in Hong Kong. He was chucked into a labour camp when he tried to escape, and then after a few years, released and basically forced to produce films in North Korea to "glorify" the nation.
At a film premier in Vienna, this chap managed to leg it to the American embassy, and was given political asylum.
Kim Jong II was absolutely convinced that this director had been kidnapped by the Americans, and was being forced to say bad things about him.
In this analogy, you would be Kim Jong II by the way. I point this out because it seems like you might have an ability to ignore blazingly obvious issues if they are inconvenient to you.
So basically, yes, perhaps the world is against you, but you sound like a man very deeply, deeply in denial about what is going on. I used to work with social services (with, not for), and they sure as fuck didn't have the time or resources to harass families for the fun of it. There was a reason that your partner and child were removed from you and put into a protected location! Do you honestly think that's standard procedure??? Do you really think the police and social services do that to every single domestic argument call they get?
The answer is no by the way.
Also, abused women have a tendency to "return to the vomit" (if you will) because it's all they know - their self esteem has been completely shattered by their partner. It's like a moth to the flame.
For the good of humanity I suggest you take a long, hard look in the mirror and think about how you have been behaving. If everyone else is looking at something and calling it "blue", and you are the only one insisting that it's "red".....
It's most probably not red.
