Make her love you, more than you love her. If you bathe her in love and romance, it'll be the fall of your LTR. No matter how much you care for her, always respect yourself first. She wants to see that, she wants to have a strong partner. You will get tested in life and tested by her, how you handle this, is important. Do new things, include her, show things she's never seen or done before. Show her how you live, have fun, live as if you were by yourself. Never become too comfortable.
