To feel attached is to feel safe and secure. By contrast, an insecurely attached person may have a mixture of feelings towards their attachment figure: intense love and dependency, fear of rejection, irritability and vigilance. One may theorise that their lack of security has aroused a simultaneous wish to be close and the angry determination to punish their attachment figure for the minutest sign of abandonment. It is though the insecurely attached person is saying to themselves: 'cling as hard as you can to people - they are likely to abandon you; hang on to them and hurt them if they show signs of going away, then they may be less likely to do so'. This particular pattern of insecure attachment is known as 'ambivalent insecurity'.
