Keep on keeping on! You did very well in letting your H go, even when he offered to stay. It sounds to me like he WILL be back, just as soon as he knows that it's his decision. The complete break from the OW, the jade ring, the promises of exclusivity and to work on your M - that's all so positive.
Now for the loving detachment. Do what you know works. You're gonna make yourself irresistable. The sad and desperate Jeannine makes him want to soothe and comfort, but not stick around for. The confident, somewhat detached Jeannine makes him want to love and be with. It's so hard to do, but you can do it, just as you have in the past. Buck up, you WILL get through this.
