Story time: I found out my fiancé's late nights at work were a second job. To pay for MY ring.

I was sure he was cheating. Smelt different, came home at 1am, phone face down. I followed him. I'm not proud. He drove to Ikeja, parked, put on a reflective jacket and started directing traffic at an event centre. A whole bank manager. In a jacket. Waving a torch. I sat in my car and cried for twenty minutes. Then I found the receipt: he'd upgraded the ring because I once said my friend's own had presence. I have never mentioned jewellery again. He doesn't know I know. Do I tell him?
