Best friend advice?

Ok...well me and my bestfriend leslie with my other best friend jackie had the best friendship ever.We love to hang out and be there 4 each other....The thing is we made bestfriends with this other gurl named melika and unknowingly we unknowingly drifted away from our friend leslie and made better friends with melika.So leslie got other bestfriends and she is not as close to us anymore...How can i make it so we drift away from melika and get closer to leslie.(me and jackie wanna be leslies friend and not melilka's)Any advice?

Have a little party and invite them all around????
