I often asked myself the same questions when my h first left. yes I let him know I didn't want him to leave (even if it were just for him to deal with his "issues") but I did not cry (well except for when he first told me and then I went and saw my baby son sleeping) I was doing just fine, perhaps it sent him the message that I really didn't care, and sometimes I wondered if I did or if he was doing me a favor by leaving as I wasn't happy either.
you may be in shock and that is why you do not feel panic, could be that he has told you there may still be hope. just know that your feelings about it can and will change from day to day, when you are doing ok you are sure to question your feelings for him, that is normal. just take time for you and reflect on what you had vs what you want in a r with your h and go from there. time=growth if you allow LL
