This absolutely is not an empty statement. Relationship problems come in many forms. For many people one of the hardest things to do is to talk about their feelings or to listen to another's feelings about themself without getting hyper defensive/annoyed (Maybe I did do this but it was because you did that; OR, I know I do this but you do that) .
Therapy can be a great help in these circumstances but unfortunately, by the time people see the need for therapy, there is usually a great deal of resentment built up that can't be removed with a simple opening of communication.
If you both have things to say but do not know how to say them, therapy could be a good idea but remember that it is just as likely to bring things to an end sooner as it is to give you the keys to resolving the issues and moving past them. Best of luck.
