I can show you better than I can tell you

Don't tell her you love her, SHOW her you love her with ACTIONS. Not gifts, not words, with actions such as spending time with her. Not being her slave, not kissing up to her, not doing anything she asks you to do ... compliment her ONCE that she looks great today in that outfit (not she is beautiful but the effort she took to look good for you is beautiful. Effort, not existance.)
