I think he is playing games..being childish.. Just act as if it don't bother you at all and it won't be fun for him anymore..

You cannot be the one to get rid of her..HE would have to get rid of her..but does he like her? If not I wouldn't worry about it....she can't get him if he exclusively likes you...in the meantime don't let her get to you..show confidance..shes actually the one jealous because you have him!  Good luck

Staph infection of your eye is contagious if its weeping or draining..don't let anyone share anything that touches your eye such as a towel etc..hope you feel better!

There is really no great way to do it..so honesty is the best policy..
