The currently airing Sukitte Ii na yo might suit your needs. It is a shoujo romance anime that follows the heroine Tachibana Mei, a girl with trust issues who feels as if whenever you get to close to somebody they will inevitability betray you. Little does she know, her encounter with popular student Kurosawa Yamato will help Mei branch out and blossom as a person who is more willing to accept and befriend others, especially Yamato.

EDIT : You also might want to give Amagami SS a try. Its an anime with different arcs for each romance option. It might be what you are looking for. It also has a second season so there is more where that came from if you are interested.
