its all good. keep up the good work. definitely moving in the right direction.
expect reactions after you're out, i'm expecting some back sliding or blow back from him. he may lash out.
and expect that you yourself will have feelings of not wanting to move back, i think you'll hit points where you'll like your new place more than the thought of moving home, and the grass will be greener for a while.
forget the what-ifs, they're only mind-games you play on yourself. you can what-if yourself straight into a divorce just as easily as what-if'ing yourself into a family of 14 or having a hairy back. its all meaningless unless your goal it to examine your fears. but it has nothing to do with reality, and you cant predict his reactions to any certainty.
his comment of one lapse of judgement does throw up a red flag for me.
and i do not think he had an A, never did and think less so after his comment.
but my red flag says he and you still see what happened completely differently. while its expected that perspectives are different, your perspectives are very different. it may have to do with time frames - he's looking at a very specific act, while you're looking at an entire season. i think it'll be helpful to agree on whats the issue, so you can work on it.
you may want to discuss this with your MC, i predict that reality is somewhere in between.
the flowers were great. and why need a name? who else are you expecting anniversary flowers from?
and i've said it before, and i'll keep saying it until you agree with me, but i think his not saying ILY or initiating ML is that he's giving you space, he's trying not to pressure. he's walking on eggshells. he's basically following DB for WASs.
