I do see a little bit of MLC lingo in there like the "walk away from the abuse", but I do think overall it is VERY positive. I do think you and him will be just fine.
His letter really gives an insight to what the MLCer was thinking.
It's wonderful that he has noticed all the positive changes you have made. Remember it takes them a while to feel comfortable in their own skin.
It must be nice to get such a positive letter after all this time.
