Think about this one for a second before making a quick conclusion. Let’s say you like the person or even love the person you’re with BUT something is missing. It may be sex, communication, romance, protectiveness, common hobbies or common interests. You are 75% fulfilled in the relationship but that also means you are 25% unfulfilled. That 25% bugs the crap out of you! You miss that area. You long for it, but it does not exist and probably never will. You have talked to your partner but it only ends up in tension and frustration. Would you go looking for a person who is a 100% match or stay? Keep in mind if you leave you run the risk of never finding that match and losing a relationship that was almost everything you ever wanted and a person you truly love and don’t want to hurt. Would you find an additional partner to fill that missing 25%? This may include cheating or potentially falling in love with another person and hurting your other partner. Would you just stay and call it good being mostly satisfied? Try to think what is fair for the other person as well. Chances are they have similar feelings.
