Undesired pregnancy on a holiday - England

I am a uk citizen living in London, I went on a holiday in Kazakhstan and had a fling with a local girl, after 8 weeks she sends me a medical report that she is pregnant. I told her I don't want a child and I took all precautions to have a protected intercourse. She wont't get an abortion and I don't want to have any responsibilities or pay any child support in future. Do I have any legal obligations? I am in the UK now. What will realistically happen if I sever all contacts with her.
