That sounds so confusing and hard for you Massimo. I can really hear the yearning and longing to be soothed and reassured by him. I worry that this relationship has the potential to do a great deal of harm whilst the boundaries are unclear. In harm I mean you getting hurt when he doesn't respond. I would really consider the pros and cons of this relationship before you continue. It sounds so very painful for you.
Could you email/ ring and say that you really need clear boundaries. That it's important for you to know what the expectations are from him too because it sounds as though you are clear about what you want from it.
It sounds as though he still has a lot of power and the potential to do harm. I know it's hard after seven years in therapy with him but the attachment is still so strong. I am glad that you can talk about it with your new t and would encourage you to try and make the most of that new relationship.
