Step Families

I feel as though I am in totally unchartered territory and would really appreciate some advice.

 

My daughter (ASD) and I have moved in with my new partner.  He understands that she has ASD and has been supportive.  However, I am actutely aware that I have built a bubble world for my daughter to inhabit and now that world is being shattered piece by piece.  She was expected to do very little for herself and the family unit when it was just the two of us and had her own TV room to escape to.  Now, she is being made to do more for herself and share my attention not just with my partner but his three year old son who he has joint custody of.  Obviously, it is not unreasonable that she does things for herself and does not always have my undivided attention but I am beginning to feel like I have let her down.  I am aware that guilt is a huge part of being a parent and in order for my daughter to grow up and function in society she needs to become more independent.  I have kept away from relationships because I always felt that she needed to come first, I am now realising in doing this I have created a very selfish person.

 

How do I ensure she starts to become more independent without her feeling as though she is being pushed out and being made to do things differently?
