Why does terminology and labels effect how a relationship between people works?

[urck]

I'm really confused about relationships... as soon as I get into a "relationship" from being single it seems that everything changes from a choice to an obligation. Is this just my mindset and perception of what a relationship is or is this normal for everyone?

What generally happens from the start of a Relationship, given time from beginning to go out, over time, people people either become close or the Relationship becomes more firm and couples find they are obligated to their partners needs and expectations, this can come about quite quickly where we feel, For example you just out with that one person you do mot use them you consider their feelings. as they will for you.
