Search Results: giving emotional support

I've been thinking about this for a while. A common characteristic among people is the want to feel desired. However, even if we are in a relationship, we feel as if we are missing something, even in good ones. These missing feelings are usually due to our own perceptions of our immediate situation, which does NOT mean our perceptions are wrong, but skewed due to certain dynamics in relationships.
In bad relationships and one-sided ones, both or one of the partners will try his or her best to find a connection mentally, emotionally, and/or physically. This should NOT be an excuse to cheat, but the reality is, life is too unpredictable with people constantly changing. Those changes would be potential triggers as to why some people are willing to cheat, but not even realize they are doing it.
I've seen a wide range of scenarios. A guy isn't getting what he wants physically from the girl, and he looks for another girl whom is willing to provide. A girl is not getting the emotional support from her boyfriend, and ends up going to some other guy for support, but will not do anything with him physically. In both scenarios, the scapegoat parties are the ones essentially become third wheels that are left unfulfilled in someway, shape, or form.

Toward the poll:
Cheating is stigmatized. However, I think this is only because our human based culture EMPHASIZES on monogamous relationships, but in the most objective sense, we are animals who have only a few main goals: eat, drink, breathe, reproduce. In a way, cheating in this situation can be considered as a natural want to fulfill are normal animalistic goals, but the it is because of our culture, we do not condone it.
