Respect yourself and expect to be respected. Sometimes people don't respect others because they really don't respect themselves. Keep a healthy social life with your friends, if he doesn't treat you right spend more time with them. Be secure enough to let go when the relationship isn't working. Spend time together doing things you both enjoy but don't expect him to like to do everything you like and visa versa. Be willing to comprise but not all the time. I heard something on a talk show about 20 years ago and have noticed it's really true, the person who loves the least has the most power in the relationship. A healthy relationship would require both to love each other unconditionally, which is rare these days.
