Pray for her, but also for her parents to be supportive, patient and understanding. I know she can’t undo what she’s done but she will certainly feel the pain later in life, especially when/if she chooses to have children again.
Shortly before we got married, I found out that my wife had had an abortion. It devastated me at the time but I couldn’t turn my back on her. It had happened a few years earlier, about a year before she had our son (she had him when she was 16, 4-6 weeks before I met her). Her “extremely religious” Catholic parents didn’t give her a choice in the matter. They explained to her that she was way too young to have a child, that her family would disown her and that no decent man would want anything to do with her if they knew she’d had a child out of wedlock. She firmly believed those things at the time (and again when she found out she was pregnant a second time, although she was in the 3rd trimester when she found out and her mother was unable to find a local doctor willing to perform the abortion) and spent a lot of time later in life trying to convince herself that it was the right decision.
Even after we were married she assured me that if she’d had two children instead of just one I never would have been interested in her. I don’t believe that would have been the case, but I think, at the time, it helped her deal with what had happened. I think she knows now that I would have loved her just the same.
Although I know she’d had problems with it at other times over the years, the real pain hit when we were pregnant with our first daughter. It came back when we found out we were pregnant with our second daughter and has hit both of us since we went through our miscarriage. It’s extremely difficult on me to think about what we missed out on. I know that only gives me a window into how hard it is for her, but I also know that we both take some comfort in knowing that both lost babies are in God’s hands looking down on us.
I pray that your friends’ daughter finds the support she needs to deal with any pain that comes later in life.
