Who are you, what age are you, are you in the household? Frankly, I think your fifteen year old sister is going to have to give birth to a baby. Possiby can put it up for adoption if your parents are open to it. But nothing much you can do, depending on where you are in the situation, is apt to work or be possible. She's got to have a place to be and support, there's very little chance you can spirit her out and get her an abortion in New Mexico and then drop her off back at home. Or just order her some abortion pills and let her go through the process without her parents knowing what is going on. There's just no easy fix for this situation. If her boyfriend is the same age, perhaps his family can get involved also, the parents may be working things out. Not sure you can just make this go away for her. It is perfectly legal for them to keep her grounded and without social media at her present age and stage in life.
I don't know exactly what you mean by who are you. I'm her sister. I'm 21. I only live there during school breaks now.
Yeah, so far all the links and stuff mentioned here seem like they've been a dead end. Truthfully I'm also afraid of getting involved more since my parents are paying for my school and living expenses.
From what she's told me the father's parents are sort of the same as ours and neither ones want to put the baby up for adoption.
