I am 33 weeks pregnant,my partner left to be in a new relationship when I was 16 weeks pregnant. I have not seen him since as he has moved away with his girlfriend. He does not contact me or ask about the baby. His family says he is happy and he will not be in my baby’s life. He is still paying half the mortgage on our house but wants me to sell up or buy him out. He will not be there when I register the baby’s birth as he will be busy. What can I do to get him to pay for baby’s upkeep?
