All things nadadaan sa maayos na usapan. But make sure that you are ready and prepared lalo na emotionally kapag nag confront ka ng asawa. I admit nakakainis nga pag ganyan ang mababasa mo, and I strongly do not believe that men will be "men" meaning maghahanap sila ng babae. That's not true. This boils down to a man's attitude, values, and conviction. Real men do the right thing.
Right now since you just gave birth, you have to fight your thoughts para din sa sanity mo at para sa baby mo. When you are ready, talk to him na. Dont forget to pray and ask for guidance and wisdom on how you will open the topic sa asawa mo. And practice self-care. :) Do this for yourself ha, not for your husband. Good luck po. I wish you well.
