Abortion

Hi everyone, this is a touchy subject for most and I am aware. When I was 15 I had an abortion since then me and the man have gotten engaged and we are very happy, this leads to even more depression about it I often wonder if we would be where we are today if we had gone with another option. He seems to be past it and I don't want to keep brining it up. Does anyone have any advice as how I can move past this, it has been almost 6 years and I still feel like it happened yesterday. Thanks for your hell
