AITA -I got banned from a house?

EDIT : IM THE ASSHOLE. Not needed to read this post. I figured out I’m the ASSHOLE.

This is in the past, so it’s kind of irrelevant, but when my ex and I were dating, we got invited to his best friend’s fiancés home. We were drinking. I was new to drinking and said something bashing single dads. All the guys there were single dads. I was insecure and trying to fit in. I forgot what exactly what I said, I was trying to make conversation. But I did observed one of the guys treat his little girl not to my liking. And I don’t think I directed the comment to him, but I should have kept my mouth shut and not been judgmental. But when I drink, I just talk out of nervousness. The fiancé then told her future husband (my ex’s best friend) to tell my ex that I’m not welcomed at her house anymore. Very understandable.

Later, I realized I was drinking too much, worked on myself, felt confident again and wanted to start hanging out his friends and the fiancé, bc my ex wanted me to hang out with his friends too, so I kept being like, let’s all hang out!

My ex kept being like, oh it’s just guys all hanging out tonight, maybe another time. Finally after a few weeks, he told me the real reason; he didn’t tell me immediately bc was trying to figure out how to delicately tell me.

But that’s when he told me I wasn’t welcomed at her house again and she asked I never come to her house again. I then messaged her on facebook telling her I was out of line, drinking and nervous but still shouldn’t have said those things. She didn’t answer, but told her fiancé and nothing came of it. I should have gone to them in person, explained myself and asked to try again with the friendship.

So I know what I said was wrong and out of line, but was it dramatic she banning me and not talking to me directly or are some people just like that?
