AITAH for refusing to help my mother-in-law after feeling like she treats me like a servant, even though my husband’s mad about it?

I’ll try to keep this short, but honestly, I don’t even know where to begin with this one. For some background, I (F) have been married to my husband for a few years now, and things have been mostly good between us. But there’s one huge issue that’s been causing a ton of friction: his mom.

When we first got married, I wanted to be on good terms with her, obviously. So whenever she needed help running errands, picking up groceries, you name it I was happy to pitch in. At the start, I thought it was just occasional stuff. You know, regular family helping each other out kind of thing. But over time, her “requests” have turned into what feels like a full-time job.

It started small she’d ask me to grab her things when I was out, or help with cleaning when we visited. But then she started calling me all the time, like several times a week, to come over and “help” with things she could easily handle herself. Things like laundry, cooking, vacuuming stuff that isn’t even urgent! I started feeling less like a daughter-in-law and more like a personal assistant or… honestly, a servant.

The worst part is that anytime I even hint that I have a lot on my plate already (I work full-time, and I have my own family responsibilities to take care of), she’ll start with the guilt trips. Stuff like, “Oh, I guess I’ll just do it myself even though my back has been hurting so much lately…” And without fail, my husband just doesn’t get it. Anytime I try to bring it up with him, he brushes it off, saying, “She’s just lonely, can’t you just be there for her? It’s family, after all.”

Last week was the final straw. I had a long, exhausting day at work, and I was really looking forward to coming home, unwinding a bit, and just having some peace. But as soon as I walk in, my husband tells me that his mom called and needed help cleaning out her attic. He’s already told her that I’ll go over. When I said no, that I was tired and needed a break, he looked genuinely shocked and annoyed. He called her back and told her I wasn’t coming and I could hear her reaction through the phone. She starts practically wailing, saying how she needs me, how she doesn’t know what she’ll do without me, all that.

After he hung up, he turned to me and said I was being selfish and dramatic, and now he’s basically giving me the cold shoulder. He keeps saying things like, “What if we need her help someday? She’s family you don’t just abandon family.” And it’s like he’s totally ignoring how burned out and used I feel.

I honestly don’t know if I’m overreacting here. I mean, it’s his mom, and family is important. But I feel like I’m the only one sacrificing here, and he’s just letting her walk all over me. AITAH?
