3rd person between couples

i just don't know why friends with boyfriend sometimes just close with me, 

they are just trying to treat me a sister like their girlfriend do, 

they are just trying to tell someone close to her girlfriend from some frustrating stories they doesnt feel good, 

they are just trying to find someone that listen to them but do not want to let their girlfriend to know about it,

they are just trying to find someone to help them to solve the problem and sort it out because friends are more easier to approach and talk with compare to boyfriend!

so, i just dont understand why, girlfriend would get jealous and do not believe their friends instead,
i know, its girl natural instinct to get jealous of, especially with their friends beside them,
i know, its easier to be acceptable reason, because friends beside them always be the third person at the end of their relationships, AND THIS IS ALL FROM TV DRAMAS! i always blame to tv dramas, because it's hardly appearing from real lift,
i know, its very BITCHY if there is.
i know, because SHE is single!!!!!! but, if you know her well, she wouldnt being so bitchy, cheap and low standard because of both of you.

it's so annoying and bad feel afterall, trying to help the relationship of a couple,
in the end, the girlfriend blaming the cause of breaking off, because of she helping out??

ikr(i know right!) boys always use the advantage of single woman especially the friend of his girlfriend,
i tried few times(more than three times), because im the only single friends that close to them, what a stupid scene!!! i can say, stupid/annoying!
boys always praise how good the girl is infront of their gf(girlfriend),
boys always confess to his gf about the girl is the ideal type of girlfriend to him.. lalallalalalalallalalala
but huh why, i had this type of feeling so many times, still SINGLE> WTF!!!

i hate being blame! and from my best friends beside me. really strange feeling! anyone telling me how the eff, is this going to be in the future,
im meeting them and i feel so shy, and always thinking about it, im taking off those stupid hell talkings, instead of talking much in the group.

that's why, i always stay far from girls with boyfriend. i dont want this happens to me again and again,
i think im born to that kind of situation.

so ladies, if you know your friend well, believe in them, and remember,
not all boyfriend is flirty kay! must always believe all mens if you do!

so mens, after reading this, please...... know what's the maximum limitations you can do to your gf's friend,
mens, stop telling your gf, that how good her friend was,
NEVER tell your gf, the ideal type of yours, especially someone she knows! she'll remember it like forever!
and most important, never fall in love with someone she knows! *okay you know about this!*
