Feeling ko may iba yung asawa ko. Kahit anong lambing ko, parang wala siyang gana. Pano ko ba siya kakausapin at tanungin kung may babae ba siya?

I don't want to sound too religious, but I suggest you pray first for maybe a few days for God to give you wisdom especially for the words to say. Mahirap kasi magsuggest kung ano ang pwede gawin, but each family has a different dynamics. And while you may have doubts now, avoid accusing him immediately during your talk kasi baka mainis siya agad.
