My best friend of 25 years was single, so i hooked him up with my gf's best friend. A year later, when me and my gf broke up (because she cheated on me), my best friend came around to tell me that i couldn't be his friend anymore…because his gf wasn't cool with me being around anymore. Turns out none of my other "friends" were cool with that either. They all dumped me to make her happy. I moved away and haven't seen any of them in 6 years. I lost most of the friends i made as an adult in about 2 weeks.
