AITA for taking my daughter somewhere when my husband and sons went on a “boys trip.”

I (43f) have triplets: Mark, Liam, and Abby (14) with my husband Josh (45m.)

Last Friday Josh decided to bring Mark and Liam on a spontaneous trip to Six Flags. I don’t like amysement parks so I wasn’t bothered by not being invited. Abby asked to go as well but Mark and Liam said it was a “boy’s trip” and that she would ruin the vibe. Abby was upset because she felt left out and I felt bad for her so I decided we’d have a day out.

On Saturday we went to Cheesecake Factory (our favorite restaurant), a local spa, and I let her have a mini shopping spree at the mall that only came out to about $150. I paid for it all since I got a hefty bonus and didn’t know what else to spend it on. She felt better after and we even had a heartfelt mother-daughter moment at Build-A-Bear where we made each other bears. We also had brunch on Sunday although it wasn’t very costly.

The boys came home last night and Abby was excited to tell Josh all about what we did over the weekend. He got mad and confronted me about it saying I shouldn’t have done that. I asked why because he refused to let Abby go in the first place and he said it was a boy’s trip and that I shouldn’t get her used to special treatment for not being involved in anything. I asked why it bothered him so much since I know he’d do it for our sons but he won’t tell me why it bothers him so much. He ended up even trying to take her bear but I wouldn’t let him.

He’s being cold to me and Abby now and I’m at a loss. AITA?
