I think it's sweet that your T feels fatherly toward you. Healthy-fatherly
Can you let the longing in, let it be something that connects you to T while he's busy with those kinds of fatherly things that you love?
Instead of fighting it, I wonder if you could you let your young self long for T as a kind loving father. Let your young self go there and feel what it is like, to hang out with T while he's doing his home stuff and let your young self be filled up and contented.
If that wouldn't be super triggering for you.
