I can understand why this feels so good..most of us day dream about such a relationship. For me I just wish my T was my mum, I adore her, respect her and look up to her so much.
Tecnically though the boundaries have been completely broken here and I wonder if in time, i you remain friends if you will need to find a different Therapist because the reason Ts work is that they differ from friends - they don't talk about there personal life (or at least not to a great extent) and they focus on the client completely. Having the boundaries means they remain objective and you feel safe from criticism or judgement.
e.g. on an outting with your T she may let slip about someone she doesnt like etc and then as a client you realise she may think these things about you - hence you start to feel unsafe.
again i understand how wonderful this must feel to have this person you idolise to a certain extent, involve you in their lives so much - it is something most of us can only dream off but there are pitfalls so please be careful
