Question about getting someone pregnant

I unfortunately appear to have gotten someone pregnant 7 or 8 weeks ago. I am not interested in her and she is very emotional and had a horrible temper. We talked and she is getting an abortion but will only do it at a very expensive hospital in LA.

I feel like I am being extorted. I have paid over $3000 and she wants $1500 more for hospital time she went in but could not have the procedure done because she was upset with me.

She threatens me frequently about taking me to court. I am not sure if I should just have her take me instead of paying more money to her.

Any ideas?
