He doesn't like the way i treat her.

I need some opinions here. I just had a complete stranger have go at me cos my best friend spoke behind my back to her saying he doesn't like the way i treat his girlfriend. I introduced my bestfriend to his girlfriend, she used to be my bestfriend. The two of us have a long and complicated history of our friendship, that my bestfriend does not know and has now wish to know as when he goes on about the way i treat her i try to explain our relationship he doesn't want to listen. In his eyes she can do no wrong. She has never been a particularly good friend to me though i have stood up for her hundreds of times and she has clung to me like a limpet (can get annoying). There is nothing wrong with the way i treat her, i am perfectly friendly to her when i see her i don't tend to slag her off behind her back (illustrating my problem i don't think this counts). In the past i have been a little jealous of her, at first i felt i was losing my best friend but i never let any of this show. I wouldn't dream of trying to split them, i am happy for them that they make each other so happy regardless of how unhappy its made me, but then he goes and bitches about me to a complete stranger who gets hold of my email address and has huge go at me over msn.

Its first love for both of them and is obviously not gonna last (don't tell me it might, cos it won't) though i wouldn't dare tell either of them that, that would be too cruel. I have hundreds of people telling me to let it run its course and be there for him when it falls apart, but i'm so inclined to give up on him the way he is being right now.

Plus a common complaint from everyone i know they won't leave each other alone, every holiday, most of the holiday he is at her house. I go to the pub with them and i don't know where to put myself cos they are permanantly attached at the tongue same at a party my parents had that i wasn't at. I and everyone else who knows them is sick of watching them suck face, they never come up for air, i'm surprised they still know how to talk.

Thanks for getting this far if you are still reading. Don't tell to talk to them, i've tried if they are together they are attached at the tongue if they are seperate they don't wanna know.
