It sounds like this is a rich area for you to explore in therapy and, especially if you put this in the context of other emotional attractions to older women you've had in the past, that puts the focus off the therapist so much and on to the pattern more generally. You guys could talk about the pattern and what it means for you.

I mean, what does it mean to focus all of you attention and energy on an older attachment figure? Do you feel you have to do that in order not to lose it? Or is it a way of avoiding a relationship with a different kind of person that somehow seems too daunting or threatening (and why would that be)? All stuff to talk about in therapy. Your first post also suggested a lot of shameful feelings....anything that feels shameful is great to talk about in therapy. Therapy busts shame. Or it should, anyway.
