I was a single mum for 7 years of my sons life..his father was and still is a no hoper..no child support, nothing.
I remember when I was 19 - he would have been about 4 months old, I was sitting on a bench in the shopping centre minding my own business and an old man got talking to me...to cut a long story short he told me it was people like me who gobbled his taxes by having a baby as a teenager.
At the time, and unluckily for him, I had read a Centrelink Brochure with statistics...and quick smart told him that 3% of single mums were teens, and the rest were made up of widows or separated older women who had left a-holes like himself! Mum was with me at the time and laughed at it..
Be proud of raising your child on your own, I now have a beautiful, loving DH who works his butt off and treats my DS the same way he treats his new DD...he doesn't call him dad as he still sees the sperm donor as I like to call him to myself..he now has another child, not with her mum either, and pays for neither child, doesn't work, and will never amount to anything.
