Good for you. You seem to have it down pretty good already.
Life doesn't stop just because they do. We need to get moving ahead a day at a time, a step at a time.
I find if I want to reach out to H by text I just make myself think about it for 5-10 minutes and try to focus on something else or come here and then that need goes away.
S and I took family vacation a few weeks back and we actually had more fun then we had in the past year because as I discovered I think H was in the midst of MLC for a year or more and last year he was always angry and very short tempered with us and vacation was a nervous wreck for all of us. This year S and I went and it was calm and relaxing. Yes I think we both missed H but I think we did so from the past memories of H not the more recent H.
