Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

 

I am sorry to hear about your predicament. You brought this upon yourself as you broke the law by fornicating with the man; now he wants to walk away from you. You are allowed to seek legal channels if he refuses to take responsibility for his actions.

 

If you are a person of faith, your primary concern should be turning to God in repentance for your sins.

 

The child needs a father, and you are right in insisting that he accepts the responsibility of a father.

 

Almighty Allah knows best.
