Bit of background info:
I am one of two girls, dad walked out when I was 4 and mum has raised us. She has a new partner and has been with him for 13 years but he does not live with us. Both my sister and I went to uni and I had planned to move in with a friend when I finished but mum begged me to stay at home to help pay the mortgage.
Roll on 5 years and I am still living at home. I have a DP of 4 years who owns his own flat but I am unable to move in with him as I have a dog (who my mum bought for me when I was younger).
Mum is now mortgage free and is comfortable financially. I am desperate to move out as feel that my life is on hold whilst I am living at home and it is really starting to get me down. I asked my mum if I could move out and leave the dog at home and she said no. Fine.
Dog has not been well lately and we thought we might lose her at which point my mum got very upset and said that she could never not have a dog and would go and get a new one straight away!!
It seems to me that mum is using the dog as an excuse for me to stay living at home and I really do not see a way out.
AIBU to want to move out and leave the much loved dog with my mum? If so how do I approach this with my mum? Sorry for the long post.
