I suspect that you are right, that H discovered things with OW that he liked and he's trying to transfer to me. I actually think (or maybe this is just what I tell myself to feel better) that it's not really anything new, he actually REdiscovered things that he and I used to have and lost. When we got together we used to email and talk constantly. He has said that being able to talk to me was the #1 thing that he fell in love with. My understanding is the biggest attraction with OW (besides physical) was also just the talking. I think the txting pictures is just all part of this communicating that he lost with me, rediscovered with her and now it trying to piece back together with me again.
I guess the best way to think about this and not get annoyed is to keep focused on the bigger picture, the progress and keep solution focused. I think it is positive progress that he is doing these things with me. And obviously getting annoyed would be extremely counterproductive and work against my larger goal to reconnect and fix our M.
