My best friend has been getting so jealous about my other friends. she yelled at me because one of my friends gave me a surprise visit last week, and it was totally unexpected! my best friend accused me of "stabbing her in the back" but i dont understand what i did wrong. the girl just came to my house for literally 2 mins. all the girls (including my best friend) were going to a party together, and when my best friend saw me and this girl arrive at the venue at the same time, she literally threw a fit! she went to the toilets and when i went to go and check on her, i overheard talking about me to someone on the phone. and when i explained to her that it was unexpected, she just said "yeh, ok, whateva, i dont give a ****" This is the second time that something like this has happened. what shall i do? to me it seems like she has no respect for me and certainly does not trust me.
