Their kid(s) will always be number one priority and they don't hide this fact. FYI they will value the kids they have before meeting you more than the children they will have with you. You are only a means to an end. Marry them if and only if you already have kids.

Getting married to a single mother is a very very big problem .

No man of sane mind will marry a single mother unless dey don use kenyanmata tie him destiny.

Single mothers?
Why should you as a man settle for less?
Smh...
Its well with our today's men forming woke.

The problem I have with single mothers is that most of them are selfish and self-centered. It's always about them and their kids.

They care less about you, and use emotional blackmail to trap you into committing your finances to them and their kids.

Some are good tho, but a vast majority are terrible, very terrible.
