If it has been 7 years and you are still getting these thoughts and images, I would think that something wasn't resolved back then. Either that or your marriage wasn't fixed in some of the ways you hoped it would be when you began trying to reconcile.
I would honestly suggest seeing a counselor by yourself and find out what is going on. It could be something as little as you are waiting for him to meet some of your needs, you are nervous that you aren't meeting his, etc. My honest opinion would be that its okay to tell him you are having a rough day and request that he be especially sensitive with more hugs, kisses, whatever makes you feel loved by him and then talk with a counselor about the deep parts. He may feel that you are never going to forgive him if you bring it up this much later. (Not saying at all that you are wrong, but if you see a counselor first and get to the root and then talk to him the outcome will be better). Best of luck honey and I hope it all works out well for you.
