I didn't see that thread helpkeepmestrong and don't know your story, but 
for all you've clearly been through.
I'm not a victim of DV but my family has been through circumstances which you can't just explain to people simply, and yes, people make assumptions daily and we are judged. It can feel crucifying at times, and I often feel myself tied up in knots, because sometimes you just cannot make people understand without "going there" and revealing all and who wants to live their life every day, bringing up painful memories, just to put people straight and "educate" them.
I do tend to keep myself to myself, take time to get to know people and cherish the close friends I do have, who know the whole story and give me massive strength. One aspect that has helped me sift the wheat from the chaff is to avoid people who gossip like the plague, for me, they can be people who are usually quick to make judgements, and are very vocal in their opinions. Oh, and lots and lots of counselling!
When you do find people to open up to though, as Goldmandra points out, very often you get a reaction of pure understandning and support, which is worth it's weight in gold, and well worth a few bad apples along the way.
