I haven't but my friend has
He has a female best friend( till date) and also had a girl friend.
According to him, the girlfriend got jealous and told him to choose between her and the female best friend.
The best friend has been with him since he was a child, he couldn't throw her away for a girl he's only met for a month. He had to let his girlfriend go. He said it was really a tough decision but he was happy he made that decision. He's currently in another happy relationship and still has his best friend by his side.
I have, and it sucked.
Friend K I had known longer, and friend S was the girlfriend of mutual friend between myself and K whom we'll call St.
K and S started clashing really bad, because St wanted me and K to be friends with S as his girlfriend so we could all go hang out together and stuff coz he was nice and sociable like that.
My friendship with K was a bit rocky at that point anyway due to unrelated circumstances and peoples, and it quickly came down to a point where K stood her ground and told both St and myself and it was her or S. As much as St valued K's friendship he chose his girlfriend, and as S had been a better friend to me in those times I reluctantly told K that I'd pick S as well.
In the end St and S broke up and I'm no longer friends with S but I'm okay with that, honestly. My philosophy is that if it comes down to making a choice between friends then something has brought it up to that point and the universe is trying to tell you something and it's better to just make the choice and go with the flow than trying to make things work out.
Yes. Two friends of mine did not like each other and each of them tried to badmouth the other in front of me and tried to almost emotionally blackmail me into not seeing the other friend any more.
It was getting exhausting and as a result I ended the friendship with both of them.
Yes, my best friend of 40 years started dating my ex-girlfriend. Neither one cared about my feelings so I stopped talking to both of them. Now they are split up and don't have me as a friend. Thier loss!
