Sansoora - I think you're talking to me (I hope I haven't got the wrong end of the stick!!)
About 9 years ago, I found out my exP had been having an emotional affair that had become a fullblown affair. I found emails from him to the other woman, and he fessed up when I printed them all out and confronted him. However, I didn't tell my parents this because I felt really humiliated by his behaviour. I know that sounds stupid, but (as you can probably tell) they are not the most supportive parents. They always saw things like that as a personal failure and I couldn't deal with their reaction on top of the hurt. When I was growing up, those who were divorced were sneered at as lesser beings who had somehow failed at life (even though their own marriage is full of controlling behaviours). So I kept quiet, got through the first bit, and then told them once I felt a bit less shaky.
By that stage, though, he'd gone to my sister and told them a huge whopping lie that was utterly self-contradictory: I was mad and overreacting to his infidelity, it was just an emotional affair. But he also told them that I was having an affair. So I decided to tell them what he'd done, to set the record straight. But by that point they refused to believe me, and they also made it clear they didn't think he was a violent bully either. They had to choose between the two stories, and they chose his. I don't know why, perhaps because they didn't really want to give me support, because it disrupted their lives? That was when they gave me the 'you made your bed' line, and when I started sleeping in my car for a bit while trying to find my own place. All the other stuff I mentioned happened earlier than this.
I struggled through the divorce and sale of the house by myself, trying to pay my half of the mortgage plus rent on my pretty basic salary. The house sale was hell on earth because my exP - now completely spiteful - deliberately left all the taps on and the plugs in upstairs and went out for the day. It was like the deluge. Fortunately we were insured but it took 6 months to dry the house out from the flood, the plaster had to be taken back to brick, everything then had to repainted. I had to argue hard with the insurance company over every tiny thing. He did absolutely nothing - he didn't even clean. When it was all ready it took me an entire week of hard graft to clean up because it was absolutely filthy. Then the market flatlined and I had to sell at a loss. When he moved out, he took absolutely everything that was still OK in the house. I was left with a couple of chairs and a baking sheet. I still have the baking sheet. I was just too tired to argue by that stage and I just wanted him out of my life.
Interestingly, my parents and my sister supported my exP all through this time - but they now no longer speak to him, because he was 'rude' to my sister. Can you believe it!! He beat me up with a hammer, but they stop seeing him because he was a bit snappy with her.
I basically have no idea why they act like this. My sister is very demanding practically and emotionally and I think they resent any idea that they should give 'more'.
