That was super nice of him (even if it is charged)
I'd say especially after this, REALLY try in the future, to trust him and in your relationship. I get that anxiety makes you question it, but it would be such growth for you to just allow things to be and see what happens.

I was actually gonna use the example of the stone but I didn't wanna bring that topic up again, but yes, he did take a lot of time out for that issue with you, and while he charged you, he CALLED you on a trip, and he replies to all your messages.... even if briefly,.... Why is it so important for him to think of you so often? I get wanting to be cared about.... but I guess for me, I really don't care if my T thinks of me 1x a week or 80. It wouldn't change anything in the relationship.

Try to go the rest of the weekend without email. Just take this as he cares, and all is well and try to enjoy your weekend. It's hard with anxiety but try to focus more on the GOOD things than the small little negative things...they usually are never as bad as our mind makes us think they are. Anxiety is evil

Hope this email can help you, keep this and READ it over if you feel unsure again in the future....
