It sound slike you got back together prematurely. You need to give it time and distance to heal what has to be healed and to let the time help you to forget negative patterns. It is normal to feel that what he is doing is "Artificial", like he does it not out of his true desire but to show you his affection. It is possible that he feels the same when you show your affection -- he may feel that you're expressing your forgiveness.
When pushed -- pull, when pulle d-- pushed. Maybe, there is no reason in getting apart again, it can hurt both of you, but give him a friendly space. Friendly -- I mean, pretend that you're distancing yourself not because he behaves like this, you behave like that, not because you guys can't communicate as it was sometime before -- but find other reasosn. Lack of time. Fatique. Business trip. A trip to a stylist. A sudden shopping necessity. Etc. Be very friendly and even apologetic: "Oh, I so much want to spend an evening with you cuddling near the fire, but I really have to go to the library tonight! I will be back as soon as I can, and we can talk and have a glas of wine, of course".
It's better not to push when either of you feels there is something wrong with the intimacy. Time will work for you -- time and your friendly "taking back" approach.
I myself in my 4th year of struggling, and only less than two months ago we started becoming physical to the point of giving each other a hug (I wanted it desperately all the time, but he never moved closer, and last words I remember-- going thre years back -- that he doesn't like to be touched). Of course, I am impatient, all or nothing -- and I get miserable when I don't get it all now. But I remind myself -- it's already a huge breakthrough after three years.
Be very careful with what you hae. when in doubt -- give yourself and your H space.
