My bf says that the only reason he hasnt broken up with me is because he sees the pion i have in my eyes,?

he says it bothers him that i dont show it. iwant to start something new i just dont know what to do to spice things up with him, or what actions to take. i was always the quiet one who kept feelings inside. and i dont want to be that person anymore. i want to express what he sees in my eyes.. i want to suprise him tomorrow when i see him. i need help!!
