I am by no means an expert, but if my H told me that, I'd be so happy that he at least admitted that he was still on the fence! Sounds like he just needs some time. Be patient. I know, easier said than done.
I think he said "I told you too much" because he maybe doesn't want to get your hopes up that he's still on the fence??? Just guessing here. I'm not the best one to advise. My H just filed for D last Tues and just told me last night. On the phone I might add. Long story of course, but I would take your convo with your H as a positive and not a negative.
