Trust is such a hard thing to gain back and he's definitely not doing himself any favors by being so unavailable. At this point though, it would make sense to talk to him directly b/c you obviously can't make him pick up his phone when you call. Maybe he just needs to understand why he should - for S's sakes and for your R's sake. He seems open to communication and sharing feelings, so that's a good thing. In general in seems like in-person is the best, but whatever you think will work best for your case. It will be hard but as long as he is open with it and you continue to be open with him, it should help your progress. You're doing great, but these setbacks are expected. Just make sure you both pick yourselves up and continue to more forward in a positive direction again.
Regarding the phone records, there's probably no point to looking at the phone records b/c you already know what they are going to show. H has already admitted to talking to her still, (although he says it is less, right?) But it is a good sign if they are fighting. You know exactly what constant fighting does to an R, especially when there is another person available who they have a good time and don't fight with (that person being you). And it's good that you took the hight road today. I feel like I've been doing that a lot recently and it really has helped smoothed things along as we try to figure everything out (I just hope I don't become bitter b/c of it tho).
And stay safe in the snow. I've been seeing in the news all the crazy weather you guys have been getting over there. In some places, it might even be a new record!
