Thank you for contacting Just Answer.
I am sorry to hear about the problems you are experiencing in your relationship. First of all it is important for you to remember that no one can force you to have an abortion against your will. This is your choice to decide what is right for you. From what you describe, this man seems to have been untruthful, most likely to both you and his wife. It appears that he is not treating you in a loving manner. To kick out someone who is carrying your baby does not sound like a loving action. Remember that actions speak louder than words. These are not respectful actions. These are serious red flags in any relationship. Remember that you deserve to be treated better, as does your child if you decide to keep it.
It will be important for you to check with your state to find out what the child support rules are as these vary from state to state. If he disputes paternity then you may have to arrange a paternity test. There should be a local listing for Legal Aid who could help you with this process.

In the meantime, remember to work on taking care of yourself and give yourself permission to make your own decision about the pregnancy. Focus on healthy activities such as exercise, eating healthy, hobbies, time with supportive people, etc. Above all, make sure you give yourself unconditional love. I wish you the best with this difficult issue. Please let me know if I can help further.
