I am looking to purchase a new bed for my self as mine is old and literally fell apart. I can still sleep on it fine and it's not a big deal when my gf is over but I really not a new bed for comfortably and a bigger space so I sleep more comfortably when she is over. My main question that involves this situation I'm in is rather this is a want or need, so how do I tell the difference between a want and need for financial decision like the one I'm in right now?
