Love Never Walks Alone

I am what my husband calls a good wife. Never check in, give him enough personal space. On my birthday, his ex-girlfriend said she was lonely, so I took the initiative to ask my husband to spend time with his ex-girlfriend. His ex-girlfriend was diagnosed with a terminal illness and wanted to live with my husband for a while. It's okay, I understand, I even bought the ticket for my husband. My husband praised me for my generosity and said that all the friends around me envied him. I told him to go in peace and come back later. After being gone for half a year, my husband finally came back. Seeing my pregnant belly, he turned red-eyed and said, "We haven't had sex for half a year. Where did your child come from?"
