Should I wait for the explanation then? I don't think you can do this.
It's elementary, my dear NetDoc. We'll begin with an example: If someone you were close to were to die, you would enter what psychiatrists refer to as a 'grief period'. Clinically, it is marked by an imbalance of certain hormones within the brain, which cause feelings of sadness, despair, anxiety, etc. Normally, a person's hormones will naturally recover and balance themselves out, however if they don't, the person is considered to be clinically depressed and must be put on medication. Clinical depression can be caused by genetic tendencies, or an extreme greif period that one can't naturally recover from. For instance, my grandmother's brother, sister, and best friend all died within one year. She entered into three grief periods, obviously, and usually entered one without fully recovering from the other. This 'dug her deeper' than what she could naturally recover from, and she now requires medication to help her recover from her depression.
The feelings of happiness and love work much the same way. Happiness is controlled by hormones within the brain, which then trigger endorphins. From the online Columbia Encyclopedia, (

neurotransmitters found in the brain that have pain-relieving properties similar to morphine. There are three major types of endorphins: beta endorpins, found primarily in the pituitary gland; and enkephalins and dynorphin, both distributed throughout the nervous system. Endorphins interact with opiate receptor neurons to reduce the intensity of pain: among individuals afflicted with chronic pain disorders, endorphins are often found in high numbers. Many painkilling drugs, such as morphine and codeine, act like endorphins and actually activate opiate receptors. Besides behaving as a pain regulator, endorphins are also thought to be connected to physiological processes including euphoric feelings, appetite modulation, and the release of sex hormones. Prolonged, continuous exercise contributes to an increased production and release of endorphins, resulting in a sense of euphoria that has been popularly labeled runners high.
As you can see, these endorphins create a 'euphoria', and/or, happiness and love. Endorphins are also responsible for bonding two people together. Nerves in a woman's mammary glands release endorphins when her baby breastfeeds, thus creating that maternal bond. Both women and men (women moreso than men) relase bonding endorphins during sexual activity.
If you have evidence to the contrary, I am willing to entertain it. It never changes God if we believe in him or not, for God is not created in our image. The truth is, regardless of your acceptance of it.
Evidence to the contrary? I cannot provide contrary evidence until I am provided with evidence to refute. Your last sentence is very true, however I hope you realize that it holds true for you as well as me.
