In fact, the longer you take, the more attractive you become to H as he sits with his desire for reconciliation and the question of whether or not you will ever take him back. Not in a 'game' sense, but for you to rest assured that you are now in the power seat and can take your time making the best decision for YOU.
Have you ever created a list, even in your head, of the changes that H would need to make for you to let him back in your life? Are they written down? A good first step would be to write it all out. On Wooba's thread I mentioned how a friend of mine was taught to write her intentions and visions of the future in the present tense. 'I am', 'I have', 'It is', 'I feel' are good starting points. From there you may be able to distill the steps that your H will need to take to reach the present tense future self of yours (oof, that's an existential mouthful, sorry).
One thing that I would request from my H if we were to ever to get to the point you are at is to woo me (good first step with those lovely flowers from your H, BTW). Date me. Convince me that you are truly the one for me. If this is really M 2.0, then why lose the opportunity for the limerence, the flirting, the sexual tension, the heady 'I might be falling in love' feelings? This is an upside to an actual physical S, you have separate spaces and can date again. There is nothing better than a great date night where you go to separate beds thinking about each other and what you want to do to them the next time you see them, right? But we're not 20-somethings anymore and you actually DO know this person, so there is none of the awkwardness of our youth getting in the way. Sounds kind of dreamy, really.
And in your situation (I am in the same) where the (supposed) lack of sexual chemistry has been used by H as an impetus for the decline in your M, milk it for all it's worth. Take advantage of that limerence, the unrequited sexual chemistry and leaving things on that last passionate kiss instead of taking it all the way. For your own psychosexual enjoyment, of course, but also as a reminder to you both that the chemistry it does exist between you two.
And as you have read in all the other returned WAH's, piecing seems to be just as hard, if not harder, than the actual BD and S. So prolong it as much as you can by enjoying the 'get to know you again' phase.
It is a long road ahead, but you have done so much work to get here!
