im confused.i thought being in a relationship meant holding hands

im confused.
i thought being in a relationship meant holding hands and loving each other every second
i mean, almost every TV show said that.
i thought the hardest part would be getting the boy but it seems now like that's not true.
and every time it gets hard i never leave i just slam a door or scream until it hurts.
but maybe i'm just wasting time hoping that it'll change, but everything already changed and i don't think its going back.
it used to be so much simpler but now i feel like its imaginary
was it imaginary from the start?
