Ladyhawke just another thought from a total outsider (if you come back)

I just wanted to say - It was never going to be easy and I can understand why you feel as you do and likewise your OH but you are both the adults here - getting jealous when you go out with your children, resenting the time he spends with his? When you boil it down, whatever the reasons you know you have to be the grown ups. None of these children asked to be born or to be put in this situation.

Sorry if that sounds harsh but this is the reality of life with with stepchildren. I'm not judging - my children have a step-father so I've made my share of mistakes too but look at it this way - things will not change until they've all grown and left home. Then you will be looking back and asking if you had both done everything you could to make their lives within broken families as happy as they could be. Childhood is precious, no one gets a second chance.

I hope it all works out for you x
