are in love w/me

hey ya'll

try to keep your replies serious ok?

i have 3 girlfriends
and i am really tired of juggling
one of the 3 blows the other 2 away in many respects and I really love her
BUT
i really like the other 2 as people and as sex partners
i am having a tough time thinking of lies to make them go away
i am at a loss as to how to do this gracefully
i was considering telling them both that i was suddenly "gay" and was having an affair with a man

i was not considering telling either the real truth as to spare their feelings

please drop some knowledge
thanks
