These are the things I never say, and never do, and wish I would:

tell you the honest truth

spend more time with you

uncomplicate these things

be there when she isn't

accept you offers, all of them, with enthusiasm

be bolder, and braver around you

tell you more

leave you out less

miss you less

hug you more

question you less

understand you better

tell you what I mean when I say it

call you more

go with you more

do what you ask

accept the silence better

love you less (so it hurt less)

like her less

confuse you less

share what I feel more

show you I love you when I want to.
