So hear me out. In the past few years, my parents got divorced and my mom, who I live with, decided to get remarried. It's been about two years, and I'm not a big fan of her husband. He's OK but he never really tried to get to know me, and he and my mother argue a lot. When our interactions have happened, we've argued a lot, and he's not been very nice. During their arguments, there's nothing too malicious, but they clearly have a lot of issues with each other and really shouldn't even be together in the first place. A few days ago, for some reason, my mom and I started talking about my stepdad, and she referred to him as "your father." I was a little taken aback. With everything going on, why should I call him that? I blurted, "he's not my dad." It wasn't an angry statement, just matter of fact. For some reason, she got really angry, and told me I was "ungrateful" and never "accepted him." She hasn't really spoken to me since. Is this justified, or am I the asshole?
