Fading away of my friendship me f(21) and her f(21)

So hey there i and my female bestie we have known each other since 5th probably so we know each other since a really long time and now when we are in college we still live in the same hostel , have lunch and dinner together. But something feels off , theres my one college bestie i made, let's call her be "p". Now my old bestfriend every time taunts me ki haa tu to uske sath hi ghum , that feels very suffocated to me every time. She celebrated my birthday in 1st year and gave me a keychain, so everytime she brings it up , humne tere liye itna kiya but tu ek party nahi deti it's not i didnt want to give i really wanted too but when we were at home something or other things would pop.

Now my birthday is nearing she brought that up again , ki tu to "p" ke sath hi ghumegi na , like you fuckin have a bf never gave me attention this whole fukin 3yrs now thats my choice with whom to spend time with , she asked me today ki usne tuje kabhi koi gift di hai i said yes , didnt say what it wasn't really gift it was a small cake she made but it was like a gift to me , then she taunted me again ki humne to di tujhe vo nai dikhi, ek party nai de sakti 3 saal se bol rahe in that 3 times 1st time i didnt celebrate, 2nd time was travelling and 3rd time i went with "p" . Now that really struct me directly like wtf thats not what friendship really is.

Meanwhile "p" showed me what really female friendship feels like, she cares for me, she never taunts me, she never said anything that felt me off. Meanwhile she never gave me that attention i needed.

It's not like i dont want this anymore , but its really suffocating , even i was planning something ki yeah i'll treat them something good this time , but after hearing that it feels no more planning anything, thats not what i expected from her.

Well she has a bf ik that you need to give time but utna ki you never took time out for me this whole 3yrs, even "p" had male friends but still she'll take me everywhere with her never make me feel less lonely ,she'll look up for me that i'm not being ignored or something,but her, she never cared about it. Can you believe she hasn't even properly introduced me to her 3yr old boyfriend atleast i deserved that much it's not like we are worls apart so now if i roam with her i don't think she should be questioning me cause i never do when she goes out with his bf.

I feel this is fading away from my side it's not like i dont want this, but i cant process things when she does that stuff.

Please tell me what should i do in this situation.
