You are right about him seeing actual reality I think for the first time and I am a little sad that he took away from it that he has hurt me, although I couldn't hide in our meeting that saying he could sell the house was hurting me deeply. He has apologised in the past during the separation and I have dismissed it as really actions speak louder than words. But this is the first time he has made an effort to text me and consider what this is doing to me and it has meant that he has thought about whether what he is doing is right and I think he knows it isn't.
Also, when we were happy and we had an argument I used to say that to make things ok again he only had to apologise and he used to say to me never to ask him for an apology and he would only ever apologise if he really truly meant it.
But you are also right that he is really doing it to make himself feel better at the same time. But I think he knows that an apology won't make it right, he is not naive. I think he somehow wants to make this right but doesn't know how. I think he is still confused...
