My fiancée has a two year old son. His father was out of the picture from three months until here recently. I love my step son like he is my own.

My fiancee told me tonight that she feels like she is a single parents at times, like she is still doing this on her own. She told me that i need to put myself in her shoes more. She is pregnant with our child, this one will be my first baby. I dont want to be a bad father to my own child, but if i cant do the step parenting thing, how am i going to be a dad to my own when he/she is born?
