What can I do if I want my daughter to stay with me?

If I live in mississippi and the father of my child (never married), took my daughter from me. Well we used to live together with his mom and he kicked me out and wouldnt let me take her with me, and i was told it was trespassing to go to his house and get her. I was told I would have to go to court. He kicked me out when she was two weeks and I was left homeless i went to live with him again serval times but got kicked out and his mom or him wouldnt let me take my daughter. i got an apartment now that i am twenty she is 18 months now. I qualify for legal aid but they wont do the case cause they only do certain custody cases. and i cant afford a lawyer and now four days ago he left with my daughter to a different city to live with his girlfriend of only a month. i dont know that girl. im running out of options and i want my daughter. What are my options I want my daughter and he is taking her from me?
