So my soon to be ex husband and I are getting a divorce. I just found out that I’m pregnant on Saturday and he just got engaged on Friday. He tells her that we last had sex in January which is not true. I just found out about her a week before I found out. He and I were still be intimate, he wants me to not tell everyone you due date and say that the baby will be a premie. I told him he needs to tell her the whole truth. Why continue to lie.
