My birthday is tomorrow and my sister said she wanted to take me out to eat so I was really excited. I said yes and told her how nice it would be get away from our mom (who I care for and lives with me) as we haven't been getting along well lately. My sister than says 'oh I was thinking of taking her and her daughter (my niece) with but we can leave them home'. I said I needed some time away from our mom so we planned to leave them home. Today I messaged her to make sure we were still on and she asks if she can bring daughter with 'as she really wants to go out to eat'. I said if she comes we might as well bring mom with. So she's waiting for me tell her if they can come or not. My decision, of course. If I say no, I'm the a**hole, and if I say yes, it's basically going to be a chore to go. My niece is 11, talks constantly and needs to be the center of attention wherever she is, my mom takes ten minutes to walk fifty steps, will probably be in pain and I can't exactly vent about her when she's sitting right next to me.
I don't even want to go anymore, I'd rather the three of them went and brought me home the leftovers. I want to be around an adult I can talk to, my life is work, going to the grocery store, taking my dog for a walk, and being around my mom. I just feel like the wind is being knocked out of my sails, she already knew I didn't want them to come, she just wants me to say yes so she can knock out two birds with one stone. If the three of us go and leave my mom home, that will hurt her feelings. If I say I don't want to go, my sister will call me 'dramatic'. I'm hurt, sad, angry and alone.
