I'm looking at his posting in a different way and it's not about referencing the release of funds. Keep in mind, when something is written, people can interpret it many different ways. My take is that at the moment, looking back, he felt like he couldn't do what he wanted when he wanted. In his mind, he felt like he always had to do what you wanted and there were arguments about such things and he also felt like you really didn't listen to what he was trying to tell you or you listened and then chose to ignore what he was saying. You made an effort to fix things, but the "fix" didn't last long and everything slid back into the old mode of operation which created great dissatisfaction within himself. He may have gotten tired of trying to get you to listen and comprehend what he was saying in his own way. Keep in mind, no one is a mind reader and sometimes things have to said in very plain speak or by actions in order to get others to look up, take notice and realize that things have to change.
Now, please keep in mind, we hear a lot of this all of the time when spouses walk out the door. They really don't have a justification, but come up w/this type of stuff to justify the walk. Whether any of what he said is true or not, that is his perception of what life was like to him. I'm sure that had he actually sat down and had a heart to heart w/you, maybe things would have changed two years ago...but there is no way to verify this. Why? Because, I think, that in the back of his mind, he was just waiting for the right time to walk. This man may have been watching and comparing you to other women for the last two years and came to realize that he finally got a backbone to walk. Your improving yourself two years ago, was just a temporary fix to all of the problems that he had stuff downed for a long time. He may have appeared to be happy, but deep down he was very dissatisfied w/his life and then finally one day, the cork popped and he knew he couldn't live like that any longer.
Again, I want to state...this is his perception. Your perception may be entirely different. Please believe me when I say this, no matter how much you pretzeled, he was going to remain dissatisfied w/his life. Why? Because you didn't break him and no matter how much you attempt to fix, you can't fix him...he has to do that himself. Once you come to realize that there is no way to fix the relationship as it stands right now and put the focus back on you and I mean really focus on you, your son and your life...there just may be a chance that he will believe all of the changes that you make over the next year or so. But, until you step back and just let him go, things are not going to change. In fact, if you don't step back and leave him be, the more convinced he will become that he has done the right thing in walking out the door into the arms of ow.
Today is a new day...cease the contact w/him and focus on you. Get rid of the self help books and focus on you and live in the moment.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
