Why are single mothers have so many demands for dating?

Seriously, if you ever read personal ads and you come across a single mother's ad you would think that dating her is some kind of honor with her ridiculous laundry list of demands. It will usualy start with something like,"you need to understand that MY kid/kids come FIRST" which will often be followed up by "I want someone who is willing to spend time with my kid/kids and you need to be here for the long haul" and then my favorite"you need to understand that I am NOT a call" First off, these women do not seem to get that the normal flow of things is that a guy meets a girl, they are 1st priority to each other for a few years and THEN they have a kid. So basically anyone who dates a single mother is going to go straight to being 2nd priority. You want us to spend time with your brats? Give us time to get to know them but seriously what is in it for us? Why don't you just ask us to donate part of our income to their college fund. Finally, you make it sound as if just because you are a single mother that you don't like . Are you going to tell me that after a hard day of work and dealing with your kid some would not be a great stress reliever?? These women need to understand that they are lucky to get any guy who is willing to put up with all of the bullshit that comes with them and their packaged deal.
