You can never be 100% certain that it was the right or wrong decision. It was something you had to do and, as hard as it is, you have to accept that it's been done, and it's in the past, and you can't dwell on it. If life's taught me one thing it's that if you dwell on something that you can't change, it makes it hard to go on with life. It makes it hard to be happy. Things happen and you can't change them now. I think that your daughter will understand because she comes from you. But I would wait until she is old enough to understand everything that happened. A child, and most of the time even a teenager, is not fully equipped mentally to grasp the whole concept. They may say they understand but they might not completely get it. As for the abortion, it was something you had to do. Never regret anything. After all, if you hadn't lived your life the way you have, you wouldn't be where you are now, and I know there are great things in your life that might not have been there if it weren't for the things done in the past. And if it was the wrong thing to do, people make mistakes. We're only human after all. We are not perfect, we mess up and fall down and in the end, we end up learning from our mistakes, not feeling guilty because we made them in the first place, but that experience gets us places. Keep your head up.
