A man offers to pay for an abortion & tells you he isn’t going to be apart of the child’s life as soon as you tell him you’re pregnant but you decide to have the baby anyway. Should he be put on child support or not? This is my situation and I really don’t want to put him on it because I feel like since it was my decision to have this baby, he shouldn’t have to pay anything, but then another side of me is like “fuck him, he’s an adult who knew what he was doing, it takes 2 to make a baby”. What would you do?
