My concern would be that the longer it takes, the less likely you may be interested in R with her!
And I think that is a very real and valid concern. I am living that now.
What I have come to realize, at least for the time being, is that my negative feelings or lack of attraction to my W right now is likely due to my needs not being met (the empty love tank/bank thing). So, while I am not feeling my feelings for her right now, they are still there, just sort of hibernating. It will take my W making deposits in my love tank/bank to awaken those feelings. But, I think the feelings are still there.
AND, this is an example of precisely why we don't trust our feelings. They will cloud our judgment and lead us to make bad decisions.
