I was also left with a newborn. I’m so sorry you are in this position. You can do it. Focus on your baby and child. You won’t understand senseless behaviour – you are right that person never really existed. You exist. Your children exist. You can be a beautiful family. Yes it’s very very hard on your own with a baby but it’s very intense and this period doesn’t last forever. They grow. Hang in there and be brave strong and patient. Much love xxx
