You have a condition, you can't feel love for anybody,Not until you met him, you finally feel something after all those years of emptiness.

he was cheating on you a year after your marriage, You found out when you hear him flirting with someone else on the phone

suddenly you were diagnosed with a incurable sickness that would soon lead to death, you haven't told him yet.

He comes home, lipstick marks all over him, He sees you on the couch a bit shocked "B-baby? you should be asleep.."
