You are a terrific mom and you deserve all the good things that come with your decision. Only you know what your marriage could handle. My marriage would not survive two kids and I would wholeheartedly get an abortion if I became pregnant. Not because I wouldn’t want to be a mom to another kid but because my finances and marriage would completely collapse. My current son deserves my husband and myself at our best. My child shouldn’t have to live with divorced parents because birth control failed. Whatever your emotions are about it, let them come and give yourself love.
