Ay sis, this is a legal matter na talaga dapat makipag-ugnayan ka sa proper authorities para ma-protect ang rights mo at ng bata. I'd really suggest umaabot ka sa Department of Social Welfare and Development (DSWD) or Barangay tanod/barangay hall muna, they can guide you on custody, sustento, at visitation arrangements, at kahit walang kasal may legal options kayo. A few of us mums have gone through similar situations kaya alam ko how important it is to get proper legal advice, hindi lang tips online. Stay strong, ma, you're doing the right thing by asking!
