I have not posted to you before but I have read your sitch and wanted to let you know you are on the right path.
My hubby and I were separated about a month then went to MC to try and sort things out but at the end of our 6 free sessions we still did not know whether we wanted to get back together or not so our counselor advised us to each go to IC to work on ourselves as well as the problems the other person was having with us. We actually made a list of the things we would need to see changed before we could get back together again.
Long story short we are back together now and happier than ever before. My hubby is still planning on doing his own IC but I know from mine that it helped clear up so many things and helped me figure myself out more and it is helping A LOT in our marriage.
The number one thing I learned is that I cannot change my husband. I can only change myself. You hear that all the time but it has to click in your own head before you can act on it.
I think you have a good attitude about this situation. Just keep those expectations low. It is very hard to do when things are going so well but they can really damage your progress if you let them take over (read my previous threads for details if you wish) I almost lost my hubby multiple times due to my impatience and unrealistic expectations that came from things going so well between us. Just because we were getting a long and spending time together did not mean that we were ready to get back together.
So enjoy the ride as much as you can. There will be unpleasent stretches but you will eventually work through it.
