Question

where is the line between flirting and making converstiaon? i get carried away a lot and tend to talk to my boyfriends freidnds and some of them have admitteied to having a crush on me. i dont watn to be a slut and date aroudn or anything, but i sometimes know wehre the line is especially when im hanigng out with my boyfriends friends. they sometimes want me to break up with them so i can datet them but id never do that.
so guys:
1)what is considered flirting
2)how do i know when my boyfreinds pal is flirting with me
3)should i confront the friend or my boyfriend

Answer 1

1)Every guy has a different line to cross here. most guys are way jealous and would consider even speaking to another guy flirting, let alone anything else. Other guys consider flirting harmless and don't care. You like have a jealous guy though...
2)Generally if a guy talk to a girl he is flirting. Unless he acts like a boring dull person he is flirting
3)You could by why bother. you will just make a big stink and maybe ruin not only your relationship but some friendships too.
