You could be experiencing an unhealthy relationship right now. When someone doesn't give you what you want or deserve, when someone denies you the affection and love that you need to feel good in your relationship it could be emotional abuse intentional or unintentional.

Sometimes the abuser is unaware of the intensity of your needs and neglect. Very often the abuser have to abuse his victim in order feel loved, important and powerful. Some people really want to see others suffering in order to feel loved themselves. If he wouldn't see you suffer then he wouldn't feel so important and loved in his own way.

For example, did you see misbehaved children? They aren't often bad people, but sometimes they do horrible things in order to see that you care and you have emotions. Parents, definitely, had moments at least once when they didn't feel loved.

So, as you can see there are many reasons for feeling unloved in a relationship. But the main reason of feeling unloved is because it's so hard to understand why your partner can't give you the affection that you want.
