my best friend is a "serial dater". every guy she dates is "the one", and they will date for 5 months max. and break up. shes been engaged twice, but never actaully goes through with it......it takes her two weeks to find the NEXT "one." when shes in between guys, she will come out with me and our friends, but as soon as shes with the "next one" she stops calling... if she DOES coem out at all, she will go on and on about the guy shes with. she has no life outside of the guy when shes dating him. what should i do ?? shes not mean or rude to me or anything, but im sick of hearing about her going on forever about joe or jim or whoever. what to do??
