Dear NP readers: Should I tell his wife?

NP Reader

Hello Naijapals, I have a situation I'd like to share with you and I would like you to share it with your readers so I can get their opinion on what I should do.
I met a man over the Christmas break on my way to Nigeria from the States. He sat in the row next to mine during the flight and we didn't begin a conversation till the flight was almost over. I noticed him catching glances and staring but I thought nothing of it till we began our conversation.

We had a very normal conversation introducing each other and I told him I lived in the states and he said he lived in Nigeria etc. It wasn't until he said he was worried and hoped his bag was intact and I asked why he was worried and he said he bought an iPad for his wife and he was hoping it wouldn't get stolen. I was shocked because he never mentioned that he was married. I became very uncomfortable because of the level of things we talked about but I reluctantly gave him my Nigerian number when we got out of airplane. He called me a couple of days later and asked if he could see me. I refused with the excuse that I had a family function to attend In the east. (He's based in Lagos) He proceeded to add me on Facebook. After I returned to the States, he would send me inbox messages and eventually asked for my American number. He called me A LOT. When he visited the states in March, he pleaded to see me but I refused. I asked him what he wanted from me and he said he wanted to be my "boyfriend". I asked about his wife and he said she wouldn't know a thing about it since they live in Nigeria and I live in the States. He sent me some very explicit pictures and tried sending me money but I refused. He told me about his numerous mistresses here in the states who he spends time with whenever he's around for business purposes and said that one might already be pregnant with his child. I'm Igbo and he's Yoruba and on a serious note, If his wife ever notices anything or sees our conversations, it would break her heart. I have his wife's contact information and I've had series of dreams about telling her because if I were in her shoes, I would definitely want someone to tell me such. Should I call her and inform her of her husband's infidelity or should I keep brushing him off like I've done and hope he goes away?

Please i need Your advice
