Single mom for 5 years

Hello! I have been a single mom for 5 years when I met my current partner. I am now 10weeks pregnant and we have huge plans for the future. Pero is it okay if I feel like echapuwera ang panganay ko sa mga plans nya for us? I mean we haven't talked about it pero feeling ko lang at close naman sila pag magkakasama kaming tatlo. What should I do to open up to him about how I feel? Iyakin kasi ako ngayon because of my pregnancy and mabilis sumama ang loob. Maraming salamat po sa sasagot! #advicepls
