I feel it's sad you don't really trust him after this long of time.... but I guess it makes sense for some people. I really recommend that book I linked you on FB. I got my copy and it's awesome. Very helpful to explaining all the attachment types in detail and gives exercises in practicing how to handle situations better with each type. I am finding it useful.
I am sorry if my posts seem harsh, I am just a direct type person. I don't really know how to be supportive very well in other ways. I also just see how much this relationship seems to overtake you sometimes and it saddens me
I've been there, you've been there with the other T.... I personally think his week vacation will be good for you. It will be good time to put your skills you've learned to use and to focus more on you. A week goes by much faster than we think if we stay busy, mentally.
Hope you and your family are well and have a great Sunday
