You see, you have to look at what sparked your relationship at the beginning, to what caught your eye in that person which made you like/love the man or woman you wanted to marry or be boyfriend/girlfriend with - so, to speak. For example: If some how you both lost interest in one another or think you aren't compatible, you have to back track to the beginning to find out what happen along the way to what have made you lose interest in your mate -- be your own investigator!
Men and women differ in their communication skills and area of interest. It is a fallacy to assume that not having the same interests mean the relationship is over or irreparably damaged by a long shot. Irritability and boredom between the two of you may be an indication that you're in a one-sided relationship or in too much of a routine.
Relationships need your continual input, or else stimulation lessens and boredom will set in. Rather than expecting to share each others individual interests, try exploring new areas to enhance togetherness. Plan activities you've never done before -- examine the newspaper for interesting events. Discuss ideas like a boat ride, sporting events, bicycle riding, tickets for a TV show or just setting under the moonlight or picnic in the park, it really doesn't matter as long as your doing something different together. A variety of activities will give you both new experiences to enjoy and discuss.
