In my experience and from the dozens of accounts I have read about it, no it’s not possible to work through something like that.
A lot of these « transference » cases are straight up addictions. The only way to stop an addiction is cutting off supply. Was that way for me. No amount of talking about it with my ex therapist was going to change anything except the state of my bank account.

From what I’ve noticed people who say they have worked through it are always still in therapy.
Not exactly a sign that things have been « worked through » imo.
