No not at all. I have a girlfriend who is a single working Mum, she and childs father separated when bubs was 6 weeks old. And I know she doesn't find it difficult at all (only odd occasion is when she is sick and would love someone to help with her daughter) she sometimes looks at me with my DH and thinks my life is harder as I have to negotiate our parenting styles, how I have a DH who may discipline (sp) something differently to how would etc. She has none of that, she doesn't have to negotiate with anyone and can raise her DD as she would like.

I think you are a credit and showing your child that you can have a good work ethic and they will hold them in good steed later in life
