This is a very common problem.Recently I went to a psychologist and she helped me a little.I`ll share with you my story. my boyfriend works on [Link to website omitted --JAG] and working here takes him a lot of time, I know that it`s very useful work so that I do not pay attention to the fact that he is so busy.We were both tired and rarely say that we love each other.so my psychologist advised to start with small things. We began to write messages to each other, draw hearts on the notes attached to the refrigerator.and eventually it has become easier to say it. The same situation with family, perents etc. SO try to begin with small things than it will be easyer. :)
