I'm new to this board but suspect I'll be here a lot in future.
My DM is a healthy 79, she lives alone 20 mins from me. I too live alone. My DBr lives 300 miles away.
Since our DF left our DM 40 years ago, I have felt "lumbered" with the emotional well being of my DM. I have taken her on holidays annually, bought her a house, and employed her as my DCs nanny. As well as the usual shopping trips, dinners, chats and check ins.
My DB has done nothing for her, ever. He phones her when he is distressed. He sees her about once every two years when his work takes him near her. He has made no attempt to contact me for decades.
Now my DM is aging, she is more needy - hip op, pending gall bladder op, and during lockdown I have done daily phone calls, her shopping, and IT support as she's got to grips with zoom meetings. My DB has not called her at all.
I have become absolutely livid about this disparity now.
My DM is now wanting to plan a holiday with me in the Uk later this years "as we both need a nice break".
I feel overwhelmed at the prospect of having to provide her holiday pleasures on top of the day to day support. I love her and she is good company but it's too much - and I'm scared that if I did go on holiday with her I'll lose my temper and hurt her, I feel so angry at having been left with her, if that makes sense.
Is there any advice you might have about how I could change things? I don't want to spoil my relationship with my DM (which used to be poor, I have learned to love her after years of therapy). I also don't want to make her unhappy and lonely and sad, by for example "making" her go on holiday alone. She would not contemplate holidays with anyone but me.
I contacted my DB about a year ago when she had her hip op, and asked if he's holiday with her. He did not respond. I contacted him again just before lockdown and he did respond and we were planning to meet. Then lockdown. As he has not even phoned her once in lockdown I'm now even more angry, but also getting desperate at being expected to do it all. Rather, I doubt anyone is "expecting" it, rather no one is thinking about me in this.
Am I being selfish? I'm lost and angry and afraid of my future as she ages and needs yet more support.
