Why I'm tired of Nigerian men using 'I'm not ready' as an excuse

Just saw another one. My friend's ex, the same guy who said he wasn't ready for a relationship, is now posting his new babe on his story. Three weeks later. THREE WEEKS.

I'm not saying every man is like this, but the 'I'm not ready' line has been used and abused. It's not about readiness. It's about who they're ready for. If it's you, they'll be ready. Simple.

And before anyone comes for me, I've been the girl waiting for a man to 'figure things out'. Waste of time and data. So tell me, is 'I'm not ready' ever true or is it just a polite way to say 'not you'?
