My husband and I had a huge argument. We went out for ice cream in the evening with our two kids (age 2 and 7). All was well until things got a little chaotic as we were leaving with my 2 yr old refusing to get into the car and me chasing after her and trying to get her in her carseat. My son had turned on the backseat light (still daytime) and I asked him to turn it off. This isn't the first time I told him not to turn on the light as it has happened that he left it on and it stayed on all night, draining my car battery. He refused and was quite rude towards me, so I told him I was going to take his tv remote away for being rude and for not following a simple direction. My husband, in front of my child, then started blaming me for ruining the ice cream trip, that I am making a big deal out of nothing, and that he was going to turn it off. I told him no, child needs to do it bc I asked him. Things just escalated from there. While my husband and I were arguing (which I went quiet at some point to try to stop arguing), my husband kept egging me and my son kept interjecting that he will get his tv, I completely lost my cool and told my son to shut up and my husband to get out of the car (he didn't). After this, we said we talk more at home and the rest of the drive was quiet. My husband blames the whole argument on me, that I ruined a nice ice cream trip, and refuses to acknowledge that he undermined me in front of my son. I apologized to my son for my over-reaction, while still maintaining the consequence of no tv, but I refuse to apologize to my husband. This isn't the first time he's undermined me (tho he doesn't agree that he is doing so). I am fed up and worried what this is damaging my relationship with my son. I feel bad all around...AITA for losing my cool?
