I have a friend (let's call her sharon). Sharon has recently split up from her partner (let's call him John) after five years living together. During this time John has been abusive, first verbally then physically. Police were involved so she has proof of this. One of the reason she stuck it out so long is that they have a 4 year old DD that he doted on.
Now she has left, his nose is obviously out of joint and he is now claiming that she is a whore and DD isn't his. He has refused contact with DD. When they bumped into each other in local supermarket DD ran up to him shouting "dad, dad", he refused to hug her and said "it's not dad, it's john". DD is obviously hugely upset and doesn't understand why she has gone from "daddy's princess" to being ignored.
John has said that the only way he will accept that DD is his is to go on Jeremy Kyle and do a DNA. He will not accept any other DNA test, says he doesn't trust them and that he will be "stitched up" .
Sharon does not want to go on JK, as she thinks that he will use it as a platform to spread more vile rumors about her, be verbally and emotionally nasty to her and she doesn't want her DD to ever see that.
John is now going around saying "well that just proves I'm right, and why does she not do it if she had nothing to hide, etc...."
Sharon is now very confused, she doesn't know whether she should bite the bullet and do it (she knows how the test will turn out so she would be to some degree vindicated) or just continue as she is.
If she was your friend what would you advise?
