Is NOBODY wrong in the post ? POST : This is all just high school, so a warning that it'll have been handled immaturely and overly dramatically.

So a very good friend of mine, call him Paul, helped a girl, call her Bella, when her friend group kind of imploded, and integrated her into ours, which is a bunch of chill dudes who play cards at lunch. For a few months, our group has all assumed that they were dating but now that we've gotten to know her, she's come to a few of us and asked her what to do about a few guys who have asked her out to formal when she didn't want to go with any of them (including Paul), which we helped her deal with. Paul was pretty upset, as he thought they were dating but Bella didn't, she thought they were just friends the whole time.

The AITA part is that after we helped her deal with it, she asked me out and I said yes since I've liked her the whole time, but just kept it under wraps. I feel like Paul feels pretty betrayed by both of us, but the whole time I thought they were dating I never showed anything and didn't try to sabotage them at all, if anything the opposite. I told Paul about what Bella said to me the day after and to my face he said it's ok, but he has been very downhearted since, and has mentioned that it's really painful seeing us together to other friends. I really am not sure if I'm the asshole here.
