I think if you just work on making a life for yourself and your baby. You will attract a better quality of men. Seems the good ones pop up outta nowhere.
After my First marriage ended.. I dated 2-3 guys that wound up just being a mess for a variety of reasons...
My father said to me one day while out to lunch with my 6 year old daughter and I "Everyman you meet ask yourself if you would be happy if your daughter was seeing someone like that"
Bam ! that's all it took.
