9. You spend all your free time with her

There are two major dangers with this one. First, you forgo your social life, which you need to maintain for your own well-being. If you don't see your buddies anymore, you should be worried. Remember, they may not stick around forever. Second, you smother her own personal time, which she also values. This formula will easily make you sick of each other.

8. You let her make all the plans

Not only do women dislike men who can't take initiative, they actually hate taking it themselves. Shirking all the decisions on to her does not emit respect or an easy-going attitude. It shows lack of backbone. Go ahead and choose what to eat, where you'll go and what you'll wear. There's a fine line between compromise and indecisiveness.

Learn to say "no" sometimes. Maybe you want to spare her feelings; maybe you want to avoid her wrath; but both are poor excuses to become a pushover. If you disagree with something, you have to tell her. If you don't like something, it's not right for you to "take it." Before you know it, you'll be her lapdog and her personal chauffeur. And all you'll earn is derision, not respect.
