Female Rabbit & Male Dragon have 2 kids (female Rat, male Dragon). Tough to get along!

Together for 10 years and engaged for 2. Children are a female rat (Mar 2008) and a male dragon (Aug 2012). 2012 was great but slowly going downhill. 2013 not so good and this year is even worse. Having a very hard time communicating, not on same wavelength at all. At this point there is no wedding date or even talk of marriage. All very concerning to this Rabbit, feeling timid/scared. Dragon acting superior, showing no love. What can we do to improve our luck or change this negativity? Nobody is getting along. Thank you!
