To benefit from therapy, you would be able to benefit from a relationship with another person. To do that, i think you have to be able to trust someone. Some people see other people as objects to be controlled, not trusted. They must be controlled, as they are not trusted not to hurt the OP.

If such a person enters into therapy, they will likely just repeat their pattern of wanting to control the partner. Or (want to) bring a problematic relationship into the therapy room to have the therapist back them up and inform their partner that the OP is "correct" (i did this, more than once).

It is hard to believe that another person can be trusted to actually care about you, if your family of origin did not model this for you. If their love for you was conditional, how could you trust them, or anybody?
