My son's father said about the same. Actually, he did not talk to me for a week after I found out and his parents offered to pay for abortion counseling. I said I would do it alone. I have in some ways, and not in others.
He is 17 now, he saved my life (I was a meth user when I got pregnant) and he is the hugest joy to his bio Dad and his paternal grandparents. She has to make this decision for her and make the decision assuming he will not help at all.
She could table the decision on whether to keep it herself and for right now be open to putting the baby up for adoption??
Now, how does the methadone use affect the baby? Has she researched this or talked to a doc? The time for THAT is NOW!
Best of luck to her. Tell her to never forget that babies are a blessing, even if she decides to give that blessing to another family.
I will be praying for you both.
