All you can do is take things one day at a time. With the locks, you had a boundary issue and you took action. That is the type of thing we should do. We don't need to do things for others.
MLC or no MLC, you did the right thing with your note. You will note very little about MLC in the DB book. Divorce Remedy has s one chapter. Because MLC or not, your observation about his being on his own and his right to make his own decisions is still valid. If it is truly MLC, he will remember your attitude. If he is mere a WAS, then future interactions are much easier.
I have an ex-wife. We have an extremely good relationship. We let each other be. Sure, we had our moments, but in the long run, all we can do is show respect for weach other as people and as parents of two sons. I know this takes two, but I have had a number of people tell me they wished they had the kind of relationship that I have with my ex. Heck, I know mat=rried people that wished the did.
