AIO getting angry on a friend with whom i shared a good bond

AIO I have female friend at work and past few days things are not godd between her and me and the reason is she is a good girl with whom other boys wants to talk to and i dont have any issue with tha but she says that i'm her safe space she and she can be her trueself around me but their is a guy from a different team and with whom she is talking almost everyday on chime(yes we use amazon chime for internal communication) and also on instagram as well and when ever he comes to office he just sits next to her. And in this past Tuesday that was the day it trigged me and that is because on that day she sits in the middle between him and me and first 2-3 hours was fine i was forcing myself to talk to her but she was just asking me questions about works thats it no other conversation but with him she was talking random stuffs and after 2-3 hours she was getting her chair closer and closer that was the part that trigged me i said her that ( contact before this for 2-3 days i completely stoped talking to her tried avoiding her and then she said to that its suffocating because I was not talking to her so i said ok i just talk to her again and what ever happen lets forget about that and she said be normal) you wanted me to be normal and when i turned normal just for trying and pushing myself to talk you. You are just ignoring me and i think i said that to loud because that person was texting her after few minutes that i think your friend is not liking that i sit with you. and when j said all this she just pulled her chair and sit closed next to me what it think is either that was just to show or maybe she never ment to make me feel that what ever that made things awkward so ok after few minutes we left for lunch together she and me and another girl who is also our friend but after coming from lunch i loged out from that system and logged into a different bay and started my work again and she come to me asking me why i changed system i just said that i was not able to do work properly thats it but she keeps coming 3-4 times after that as well she also texted me on chime but i ignored her text and after that i wanted to talk about all the thing but we didn't left alone their was 2 other friends with us as well so i didn't say anything to her and after that on the way back home when i was sitting in the cab she texted me what happed and why i was i liked this so told her that everything that what i feeled that she only talked to me when there was no one just to cut some time on the work so that you dont get bored and she said this not true but the thing is that day i felt some that and that is i felt like i was begging her to talk to me and i know that I'm not a funny person i dont flirt with anyone (i juat dont know how to do that) also im not that good looking not tall ether darkes skin tone skinny as well so i can understand why should someone be interested in talking to me but that was the trigger point at one point you are saying that im a safe space and on the other hand you are treating me like this and on that day over the text she finally said lets end this and i was like ok but that day i got an anxiety attack because of that was not able to sleep or eat anything so decided to say few more things which was left and i didn't said over the text so decided to say all the things face to face.

So am i overreacting or if not that what should i do about this and if you know why I'm feel angry or is this even a reason to get angry 🤔
