Don't be so down on yourself. You are human. SUPERHUMAN in this case
Hmmm, no not nit-picking at all....once again, you're being human to feel hurt by his comments. I would feel hurt too. BUT, I think what he is trying to say (sometimes we don't know what we say is stupid)....is that he is glad for the hardship he encountered, that OW was a catalyst for, because he had to dig deep, to grow up, to see a mirage and see through it, to see his M for what it was and fix it. I too am glad for the hard time we're going through, and said it to H....then I realized that it sounded like I was happy that I screwed up or that we hit hard times....I said that I was happy that something made me focus on making our M better, on making me better, but I would not abuse our M again. I was happy that I could see that just because your M goes through hard times, does not mean that it is not strong. We rediscovered lots of great things about our feelings and us.
It bothers you, so gently bring it up. Next time he says it again, ask him what he means--gently. Ask him if he means that the period itself was an eye opener and good for your M and the new and better him. Tell him that you want a M to him where you can also be supportive of the best him.
