You chose to date a married man and neglected the biological reality of you being pregnant.
What you need to ask yourself is, why would he be faithful to you, assuming you stayed with him?
If he has children with his wife, is he in their lives? Is he providing? That will give you an indication of how he might treat your child.
I am currently pregnant with a semi-married man. I call him that because he has not yet paid dowry for the woman, but they have a child. After the wife knew I was pregnant, she said she was leaving. The husband is not committed fully to either of us, he is still sleeping with other women. Should I close my business and move to another city, or should I go back to him? Bear in mind the man told me he will be silent at work and it got me thinking he won't ask how me and his unborn baby are fairing on, and to me that feels hurtful. For the sake of my mental health and my unborn baby, please advise.
I empathise with you for the dilemma you have found yourself in. I don't believe we have something like "semi-married," and paying dowry is not the indication of permanent marriage either. You invaded someone's marriage, and you have to be prepared for the consequences. Whether the wife leaves or stays, it has to bear some casualties, since you already mentioned that the man was still sleeping with other women. Either way, be positive and sober as you forge a way forward. May you find a place in your heart to forgive yourself, adjust and advance.
