AITAH for telling my wife she’s not a “single parent” just because I work long hours?

My wife (29F) and I (31M) have a 3-year-old son. I work 10-12 hour days as a contractor while she stays home. Lately, she’s been venting online and to friends, saying she feels like a single mom because I’m “never around.” I get that she’s overwhelmed, I am too but I’m working my ass off to keep us afloat.

The other night, I heard her refer to herself as a “solo parent” during a Zoom call with her mom. After she hung up, I told her that I didn’t appreciate that. I’m not partying, I’m not neglecting our family, I’m working. She said I’m being defensive and that she “feels like a single mom” because she handles everything alone at home.

Now I feel guilty. I don’t want to invalidate her, but I also feel like she’s ignoring everything I do. AITAH for calling her out?
