AITAH for throwing my friend’s insecurity in her face after she disrespected me and brought up my past ??? Or was her behaviour entitled??

For some background: I (f21) will be meeting my high school friend after 3-4 years which happens to fall on the same day as my friends birthday so we all decided to combine both the occasions.

Last week me and one of my friend (f20) the one who's birthday is coming up met separately as we came to town early and spent the whole day together. I thought all was good and we had a great time. Cut to she sent me this text and I am baffled to say the least asking me to wear something that makes my boobs look smaller and squeeze them so I don’t make anyone uncomfortable. When I called her out on being disrespectful she snapped and brought up my past and how everyone had seen my titts already and I was shameless insinuating that I want everyone to see them and how I showed it to everyone so they are not private anymore also saying that she only after meeting realized how much bigger they had gotten. In the end I said something mean which I know she is insecure about basically asking her to shove her party up her ass or rather try holding it with her flat chest”

but not sure what to do nextor if I handled the situation correctly? Also was it too much to say something hurtful about her insecurity of being flat chested out of spite after she brought up my past ??

She's now threatening to uninvite me if I don't apologize. I'm really not sure what to do because I was so looking forward to seeing everyone, and this was the only day that worked for everyone. I feel really disrespected, but I don't want to miss out on the reunion.

P.S. I have screenshots, and I’m willing to share them part. I’m not allowed to do so on this thread.

You can ask me to share or you can check as they have been posted.

Edit: I just wanna say that my size is 44H so no matter I wear they show and I have no way of “hiding” them and I only every wear plain T-shirts preferably black and sometimes even when I do wear tank tops I wear shirt over it

This is a repost after sometime cause I am still not able to get the situation out of my head. The other post also has screenshots and update !! If you need screenshots for more reference please DM.

Sorry if it feels disingenuous that is not my intention I just wish to get more opinions on the situation.
