Another limitation is that this research is correlational not experimental therefore cant claim a direct link towards early atathcment styles and later relationships. For example it is possible that both attahcment style and love are affected by other factors, kagan proposed the temperent hypothesis which suggests innate temperament of a child affects how a parent responds to them and may determine early attachment type ,their individual temperament may explain issues (good or bad with relationships) with relationships. Therefore because there could be other contributing factors a simple causal relatisonship cannot be established.
