I have 2 girls, the oldest is 19 years old and the youngest 17. They despise each other despite being joined at the hip up until perhaps 1 years ago. At that time the youngest met a guy that is horrible, he continually breaks up with her and she runs back. This guy has dumped her in the city late at night without her having any means to get back. She did not tell us anything but my oldest daughter knew and told us. I then accidentally let out that I knew and with their only being one possible source, the fighting started. This is not the only reason they have fought.
The youngest's boyfriend lowers her self esteem and has done a great job of separating her from us and her sister.
I need some way to get them back together. I tried speaking to both at the same time saying this can not go on but that made it worse, they screamed at each other and one said "you are not my sister" and the other "I hope you die". Lovely things for parents to hear.
My wife and I are really struggling with this. We have done counselling but that did not help so much. We have actually split up for a few days due to disagreeing on the way to deal with the problem.
The way it is now, they will end up not up as siblings and that is not acceptable for us.
Please help if you can, if you have experienced the same thing. Just getting them together and talking to them about the situation was a disaster.
Thanks
