I have a 15yr old DD with my ExH. I have a new partner of 11 years and ExH married his partner of 14 yrs last year. I note that there has been quite a bit of stick on the subject of step parents of late so I wanted to say...
My DD has 4 parents -me, her Dad, her Step Mum and her Step Dad. She is bloody lucky to have 4 people who love her and put themselves out for her and we tell her so. I am grateful that DDs step mum is someone with very different interests to me and therefore can show her a different view of the world...I am her 'real' Mum but guess what, my way is not always the right way and my DD benefits from understanding that.
Step parenting is a hard job, you don't always get the unconditional love and often get a bad press but you have CHOSEN to love our bio-children, be there for them and raise them into responsible adults. I for one am grateful.
I hope you guys take this in the spirit I mean it - its not meant to be patronising or anything, I just really hate seeing what some of you go through.
