I have to add.. I think you should look at your list from a DO list. Shift your thinking and come up with the opposite..
Like "don't make him the center of your world" Instead do this: "be yourself, and be independent, in spite of how much you love him, hand onto your individuality and make your identity and goals in life independent of what he is. As a loveing partner you should accomodate the other not change them. With a good partner, you will be allowed to be your own person.
I'll be honest I almost responded to every single one like this but the truth is no one wants to read my novel

at least I don't think so. Plus. Because. LAZY.
