You tripping. Single mothers have 3 tiers in thirstdom:
1. Dude has no other options.
2. Dude also has kids
3. She's such a catch even with kids that if she did not have any, she would be the unicorn.
Very few things are offered by a single mother that you can't find from a childless woman. There is nothing wrong with single mothers, but for most dudes, they are the partner of last resort. They are essentially that moment you realize you can't beat contra with three lives so you have to use the 99 cheat to get ahead.
