So I (32F) have been with my husband, David (36M) for 4 years married for 2. We met at a cafe in our town when we found out we had the same order. We sat together and talked for hours. When we met i was pregnant with my daughter, Raelynn (5F) from my ex boyfriend. We started going out and 2 weeks after i gave birth to Rae he asked me to be his girlfriend. After 2 years of the perfect relationship, he proposed and asked me if he could moved in. I agreed since I know he had been going from couch to couch. So fast forward a couple days ago, I got home from work, exhausted. So I charged my phone because it had died and i had a missed call from Rae's school and a voicemail so I listened to it and apparently Rae had pushed a kid down. I then checked the camera i have in Rae's room. After David had picked her up from school and took her into her room, he hit her. Not beat her but he whooped her with his belt, which he knows I don't do because I read somewhere that if you hit your kids, they become scared to make a small mistake because they think that somebody will hit them, so I've never hit her. And I know I'm going to get criticism for that but instead of hitting her I explain to her why she is in trouble then I ground her from outside and take away her screen time for a week or longer, it really depends on why she is in trouble. So when my husband got home from the store with Rae, I told her to go to her room and do her reading (if she wants screen time she has to read for an hour), then I confronted my husband and asked him why he would hit my daughter if he knows I don't do that and he just said "she needs discipline, Sam." I told him "It isn't discipline if she becomes afraid of you." I said to him, trying not to raise my voice. "You're overreacting. If you don't like the way I parent her, then send her to live with her dad." He said, shrugging like he didn't go against my one rule for when my daughter is in trouble. "And if you don't like the way I parent her, then you can get the fuck out of my house." I said, getting angry that he was taking this as a joke. He simply shrugged, grabbed his coat and left. AITA?
