H had A, ended badly, fog clearing, need support

[GreyMatter]

ok in light of the dreaded email yesterday we have been able to discuss our R a bit. I said I was sorry it was hard for him to tell me the exact details and he said sorry for it making me feel bad.
I said that it made me feel a little jealous that 2 things were done with another instead of with me. of course, but said it very calmly. Also that even though there were negative feelings tied to it I was happy and really appreciated the honesty and transparency.
He said he has not replied to her and in fact made a comment this morning before leaving work about it being hard because of how it made me feel not him?? He then sent a message saying he was sorry and he isn't good with his words and gets lost. I know now the R talk needs to die off now as he has reach his limit but he has at least shown signs of compassion. I can still see a little tiny glisten of obnoxious behaviour when he acts a little selfish but overall it seems it gets less and less.
I feel like I may be getting myself into a trap of talking to much though as he opens up we seem to be talking about sooooo much. He has never really shown signs of great anger toward me and definately no degrading language.
We laugh and have a great time and he still, as per most of our relationship regards my opinion and wants to know my thoughts on news kids etc.
I had said to him I'm glad to get a few things out in the open and what possibly was wrong to ensure moving forward we don't find ourselves in that same place. (made it sound like other partners not each other) He replied that he really doesnt know what went wrong. ???? He has always maintained this bit - that I have always been everything and it has been him and basically his C said he has alot of personal issues. In the beginning I felt like this was a cop out but now I almost see that he genuinely thinks it will happen again and doesnt want to hurt me anymore???
