Full Of Doubt And Regret

I am pregnant, I am a lesbian in a LTR with a first class woman. My pregnancy is via a sperm donor. My confession is that I cannot bond with this baby inside of me. I made a huge mistake choosing a sperm donor not knowing the man, not having the father in my life or the baby's life. I am ready to get an abortion and start over. My partner feels different, she did the research on the donor sperm.
