If I were my mom's friend in 1984/5, I totes would've told her to get an abortion. So she could finish school. So she could not be tied to her current boyfriend forever and ever. I would have driven her to the clinic and helped her pay for the procedure.
And that is with the knowledge that my parents' marriage ended up great. And my life is awesome and I love it. And I have a great relationship with my parents.
I would still give exactly the same advice. Because that decision had absolutely nothing to do with me, and everything to do with her. She was not choosing ME or her life, she was choosing not her life (as she knew it) or her life. Adoption would not have been an option with either of their parents involved (and they would have been involved...trust me). I personally believe I would've been born another time, but that's just me.
I spoke recently with a friend who's pro-life because she was adopted and could have easily been aborted instead. I get it. That's an intense thing to think about for your entire life. But I dunno. I could've been too. It's true of every person, they just aren't always so aware of it. Keeping a baby is always a choice, on some level.
