My parents separated when I was around 25, Mum became partnered within a couple of months of leaving Dada (whole nother set of issues there) she has now married this man. He has 1 son from his first marriage (Mum is his 3rd) I have only met him once which was at there wedding. Don't have anything agains him as I don't know him. I don't consider him a step brother, just as I don't see Mum's husband as a step father. I think if my parents separated when I was still a child and the new partners played a part in my unbringing I might feel differently.

Dad on the otherhand, well lets just say he is having a lot of trouble letting go of it all, lots of bitterness in him. Bit sad really but he won't help himself.

Oh must say Mum's husband is quite good with my boys, he isn't called Grandpa they call him by his first name but he tries hard with them which is all I can ask.
