I'm really struggling with family dynamics and would appreciate some advice. I'm in a same-sex relationship with my lovely partner, but my parents were horribly homophobic. They rejected me entirely when I finally came out to them at 40, and were horrible to DP. Dad died three years ago, and since then Mum has gone rapidly downhill with multiple health problems including dementia. DP and I have been, by default, her only support for the last two years. For the first 18 months she lived an hour and half's drive away from us, until after various crises we arranged for her to go into a good residential care home in our town, because we were the only ones stepping up when things went wrong.
When she lived at home, DM was in close weekly contact with her sister, her SIL and their families, who all lived nearby. My 40 year old brother was living with her on and off when it suited him, for months, with her doing all his washing and cooking and not charging him any board. Since she became ill, he's had nothing to do with her. He hasn't visited her, ignored her recent 80th birthday, and doesn't reply to my emails. He's not been in touch now for around a year.
Meanwhile, the extended family have similarly left DP and me to it. In the last year, her nieces have visited her once, her sister not at all. Her SIL (my aunt) and her son and DIL have also visited once. This weekend, SIL & family all came to a festival in our town, down the road from mum's care home, and tonight I got a breezy text from my aunt saying she hoped she might have run into me and DP there, but it was very busy. They only let us know they had come after they had left.
I just feel devastated. Looking after DM is hard work: she lurches from one health crisis to another, and has just come out of two weeks in hospital. DP and I were daily visitors, and her only visitors. I have had no support from any of my family, and they have all been close to my parents in the past, and to me. All I get from them is the occasional text, which feels like them checking up that I'm fulfilling my daughterly responsibilities.
What should I do? DP Is my only support in all this, and that feels so sad and so unfair.
