AITA for not being happy about meeting the woman my dad has been seeing?

This is a community like r/AmITheAsshole, except unlike that subreddit you can post interpersonal conflicts. Anything that's AITA including relationships, hypotheticals, even posting about Scar from the Lion King and trying to convince redditors that he was not the AH. AI scenarios/posts are not welcome or tolerated. An elaboration on our rules can be found here: https://www.reddit.com/r/AITAH/wiki/index
