I think the wanted something and the person sold it to her. Apparently maybe she wanted a better life outside the country. The urge to leave Nigeria is now huge, sometimes people use this as a scam method. Most Nigerian young ladies wants men who are overseas, and a potential scammer already knows this.
The lady would think "what's sending him 250k, if he would eventually take me abroad" you know, something like this.
These women do the mental maths and they feel that they'll eventually gain at the end, so they just do it anyway.
For the lady, it was sad to see that she was in love, but sadly she was sold the dream she wanted and she got hooked
Yeah you are right, she wanted a man who was better than her, all ladies want this tho
and even though the signs were glaring at her, she ignored them until the guy confessed
I think she chose to not believe your warnings or the red flags. In reality,there might be regular and well-meaning young men around her who might want her, but she might probably reject them all for a person as that scammer. Some women are like this.
