Can I sue if I am pregnant, my ex-boyfriend wanted me to have an abortion and I decided not to?

It would be wise for you to get a lawyer in this situation. Likely, there will be little you can do before the child is born. Your ex-boyfriend will be responsible to help you with the financial support for your child. He may intend to challenge the claim that he is actually the father to try to?avoid that responsibility. Assuming he is the father, after the child is born you will need to start a support case.
