there are three types of attachment
Keyword attachment there are three types of attachment. One is secure attachment where people assume that they are worthy of love and others can be trusted to give it to them. This belief becomes an unconscious template that trickles into all their relationships, leading them to give others the benefit of the doubt, open up, ask for what they need, support others assume others like them and achieve intimacy. The second is anxious attachment where they assume that others will abandon them. To keep themselves from being abandoned they act clingingly or overly self-sacrificing through accommodate others or plunging to intimacy to rapidly. The third is avoiding detachment where they are afraid that others will abandon them but instead of clinging to avoid this outcome they keep others at a distance. Intimacy signals to them that they could be hurt so they push others away and leave relationships prematurely

And remember what everyone, underneath, is really after in studies and work and friendship and marriage alike: a place, and a person, with whom they can finally exhale and feel they truly belong. It helps, too, to understand that we each carry an attachment style learned long ago: the securely attached assume they are worthy of love and trust others to give it, while the anxious cling for fear of abandonment and the avoidant push people away before they can be hurt — and knowing your own pattern is the first step to loving past it. And bring humility to all of it, because humility is profoundly pro-social: accurate self-awareness, modest self-presentation, and a focus on others are exactly the soil in which friendship bonds, happy marriages, and forgiveness all grow. — Friends, Community & Society (Relationships/Community/Society)
