Midip, I think Jennifer gave you some really good advice. Take things slow, OK? I sense that slowing things down might be another 180 for you....maybe?!
It seems that your H. is genuine in his desire to come back and to contribute in a meaningful way to your relationship. Would it be helpful to you to write a big list of all the things you would like to ask H. to do, priorize them, and then seal them in a time capsule for awhile? To borrow the analogy that you used on my thread where you likened your H. being back to a can of worms awaiting dissection, remember to just deal with one worm at a time!!
When does your H. get back from his eye appt. in London? Will it have stirred up feelings of loss for him?
Courage, Midip....
