I am a 19 year old woman who has grown up without a father figure at home. My mother has been single since my parents got divorced when I was very young. She doesn't have any friends to speak of, and while her parents are reasonably supportive, she is still deeply hurt by mistakes they made during her childhood.
Over the last 18 months or so I have realised that in some ways I may have adopted the role of a spouse/partner/equal to her in the household. I don't think it's particularly healthy and I've become aware that it's caused me a lot of pain. I'm not angry with her in any way as she has been through an awful lot and I'm so proud of the way she's handled being a single parent with very little support. However, she confides in me (hence I know about the hurt she feels from her childhood, and details of what happened between her and my father, and how she feels about her friends, or lack thereof), and sometimes I feel responsible for ensuring she is not alone at events we attend together when perhaps I would like to be trying to make my own friends. I also feel like I have slipped into a role of siding with her when it comes to her decisions regarding disciplining my younger sibling, when actually I am a child (rather than a parent) too, and therefore an equal to my sibling and not my mother. I'm not really sure how all of this has happened, nor how to fix it. How should I deal with it?
