I don't think most people are really saying they're glad OP is getting an abortion because that's the best choice in general, they're just happy that she was able to reach the best choice for herself and that she's comfortable with it. The same thing happened a few weeks ago when someone posted a secret about being a teenage mother who was happy with her choice. A bunch of people told OP they were happy for her for doing what she felt was right even though others didn't agree with her choice. Same thing that's happening here. I'm pretty sure there was a secret a few months ago where someone mentioned giving up their child for adoption and the reactions were pretty much the same.
