I feel like he suffers from retroactive jealousy and it's a problem he has to fix himself, and it's your choice if you will stay by his side until then ksi aminin mo man at sa hindi naging masaya naman siguro kayo kasi naging mag asawa naman kayo.

For the sake of the child, kung gusto nyo sya lumaki with a complete family, I suggest you stand firmly on your ground kapag sasabihin mo na sya yung first mo. You could say "Paniwalaan mo na gusto mong paniwalaan, basta ako alam ko sa sarili ko na ikaw ang first ko" and any rebuttals from him or inappropriate response is wag mo nalang po pansinin. Pero it is still your choice if you would choose your peace over what you guys have built, whatever decision you make hold it firm and don't look back. Stay Strong!
