Farmer boy Lee -
so good to hear that the time with your brother went as well as it did. i was very concerned. sounds like one key was trying not to have expectations that were too specific. glad you were able to do that. of course the anxiety is harder to control.
it does sound like you have made some progress here. not least - the fact that you went through a very triggering situation for an extended period of time and didn't fall apart or melt down.
another great point is that he didn't deny anything - and seems to be leaving the door open to further discussion in the future - that is pretty significant - considering that you have lots of support and have been working on this for some time - and apparently he has not had that.
i respect and admire you for having such mercy on him and would hope that he recognizes this too. that might be a means of strengthening your bonds. it would be wonderful if you could support one another.
stick close to "home" and take it easy for a while, if you can. in my experience, there is sometimes a big emotional let-down that follows an intense event like this. we are here for you.
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
