If I may put in my two cents: We continued to ML after I found out about my H's A. At first, it was because we were going to reconcile. Then, it was a way to feel close to him. I also had a DB coach recommend what ROOT pointed out in Michele's article - that ML was a way to connect with my H.
Key points to consider are whether there are other signs that your H is moving toward you. In my sitch, we were/are still living together and there were other positives. HOWEVER, we also got to the point where things weren't changing and my H wasn't making a decision one way or another. So, I guess my point is that in some situations it can be a good thing but you must be open to cutting your H off if it doesn't seem to be bringing him closer to you.
