For any relationship to thrive, to last, communication between partners must be tops on their relationship priorities. After all, how can you know or understand your partner better if you don’t talk? Sure, there are things about your partner that you can learn even when you don’t talk but there will be more things about him or her that you will get to know about when you talk.
And how will you deal with disagreements or conflicts when you don’t communicate? Burying down feelings, irritations will force its way back up and some times during the least expected moments. Conflict resolutions happen when feelings, thoughts are verbalized.
Both partners really have to work on their communication skills for the good of their relationship.
