Well: attachment patterns are a result of our upbringing. Who we do or don’t attach to is a direct result of our interactions with significant others in our formative years. I’d call that transference. When those early interactions were problematic we have difficulties trusting or connecting. In the same way healthy patterns are transferred too; they enable us to trust and connect. I think the more important point is that transference isn’t necessarily something to be overcome, it’s just a part of human interaction that we can understand and learn to recognise, which can be useful. When we fall in love (also outside of therapy): that’s transference... it’s just not thought about in those terms because it’s not problematic there. https://en.m.wikipedia.org/wiki/Transference
