The Teenage Mind

I work with a group of teenage girls (from age 13-18... from the tougher parts of Dallas...every city has a bad area or two) about twice a week. Every week I give them at least one day to just talk about the issues that they face, and how they try to deal with them, then I try to give them alternatives if needed. I also try to get the parents more involved in these girl's lives. Some of the things these girls talk about would blow your mind! They are able to confide in me, and sometimes keeping their secrets becomes a difficult task, when I know what they are doing is harmful.
I was faced with two hard situations yesterday.

Situation #1:
A few weeks ago, this girl came to me....A 13 year old girl is having sex with a 15 year old boy, and I know the mothers of both kids fairly well(we go to the same church). I talked to this girl and asked if it was okay to sit down and talk to her mom about safe sex, birth control, and abstinence(if she would consider that). She didn't mind. The first question that came to my head is, how can you have a 13 year old daughter in this day and time, and not have already talked to her about sex? But anyway, we are talking, and I can quickly see that this mother is in complete denial. She refuses to even consider what I am trying to say to her, gets upset and leaves with her daughter. Now I would be happy if my daughter came to me and told me that she needed help BEFORE she gets pregnant or contracts an STD! The girl came back to me yesterday and asked if I could take her to get some birth control pills. I instead, gave her a number and contact to one of my friends at the local free family planning clinic, and told her to go see her. She then hangs her head, and as she turns to walk away she says, "I knew you wouldn't do it." I explained to her that I didn't feel right going against her mother's decision, but I was offering her help at a place where she didn't need her mother's permission. She said that she didn't want to go alone.

Now my dilemma is, what should I do? I have a mother that is in denial, and has forbid me to talk to her daughter about sex. On the other hand, I have a young girl who is crying out for help. What would you do in this situation?

Situation # 2
At the end of each Thursday session, we give one girl a change to ask the group a question, and we all come back and discuss our answers the following week. At the end our discussion yesterday, a girl brought up the subject of abortion. She wanted to know who God would hold accountable for the death of the unborn child. She said she already knew that the mother was sinning. But, wasn't the doctors sinning also since they were actually taking the life? And what about the nurses who chose to work at the abortion clinic and prepare the patient for the procedure? I am pro choice when it comes abortion, but this goes beyond that. I feel that every situation deserves a different outcome(When you factor in the some of causes of unwanted pregnancies).
This one had me puzzled. Thank goodness I have a week to think about it!

What are your thoughts on the two situations?
