Does my brother need psychotherapy to cope with this girl rejecting him because he's talking weird?

I think what needs to happen is have a sit down with him and just tell him to get over it. It's not going.to be the end of the world just because one girl rejected him. I've had this one girl I was head over heels about reject me and, suffice to say, I did go a little stir crazy, but then realized that I can find other girls that her. Granted, not the same person, but oh well.
