What should i do..? (involves a problem i have with my "friend")?

i have this friend (she can be bridget).bridget and i grew apart at the end of grade 9.after we grew apart, bridget who was also friends with one of my friends from grade 1 (she can be jessy), told jessy that i said a whole bunch of mean things about her.bridget is the type of person who can make you believe her with extreme ease.jessy believed her and stopped talking to me. i told one of my closest friends (she can be jenny), and jenny and i explained to jessy that i never said any of those things.jessy 'forgave' me, but continued being friends with bridget as well.this brings us to tonight.i was talking with jessy on msn, she was acting very strange, again stopped talking to me for no reason.'coinsidently, a minute or two later bridge starts talking to me, bringing up the subject of jessy& letting on she knows nothing.i can't handle these constant problems because of bridget anymore.should i stop talking to bridget and get her out of my life??and what should i do about jessy??.... :(
