Daisy - it is up to you, but I don't think the desire for goodbyes is weak. It is human.

There are therapists of mine like DBC that I don't care I didn't have a closure session with because I didn't give a damn about her. There are others that I really wished I did, and with No. 3 I pursued that and I am glad I did. Despite still missing her six weeks on.

I won't lie, it will hurt either way. But you should decide based on what you need, without the lens of self-criticism.

And just because you go back to end things doesn't mean you're not being resolute in your decision to terminate.
