I Have A Dilemma

Im speaking fo my brotha. Alright my brother is n love with two people. At least I think so. He's n two relationships with two different people. The first is someone that is a high school crush, they marched together n the band and everything. The other is a person he met while n skool (he'z still n skool). The only thing is the high school crush is worried that she might be loosing him to this other female. The high school crush knows bout her, but his girl he met while n skool PROBABLY doesnt know bout her. Shes n love and everything; even though he'z can work a nerve, she really cares for him. What shall she do in order to assure herself; he feels the same way she do. Can someone give me some advice before its to late???? PLEASE

Dump them both at the same time. This will end all problems.
