Of course we can improve the couple's communication, it is very usual that at the beginning of the relationship the communication is good, this is because as the relationship is new, each one gives the best of himself so that everything works perfectly, however I think that as the monotony enters the relationship the discussions are appearing making communication is what first begins to deteriorate, however with a positive attitude it can be improved.
The love of a couple makes it necessary to improve communication, since moving forward without good communication is almost impossible. Bad moments in a couple's relationship should not be considered a primordial entity to break good communication, on the contrary, couple's problems should be considered as the precise moments to have a good communication and face the problems as challenges that can be overcome in the short term.
To improve the communication in some key moment of the relationship the first thing that must impregnate is the need and disposition of wanting to improve the communication, reason why the most problematic thing is that some of the two can propose to the other one to be able to converse on the subjects in which it is wanted to improve, for it is important that conditions are not established that can derive in blackmail, on the contrary they must be proposals of free nature that help to the growth and development like couple.
