I have a friend who is in this situation right now, their kids are all grown up not only once did she discovered his partner is playing with other team up to the point even their son has seen the other party riding on their father's motorbike but still denied. He has the nerve to say to his wife "nawala na ang love kay nitambok na". When he was sick before my friend took care of him but now that he had recovered, back to his old vice again - womanizing.
