I think this could be a pivotal moment for your M. It's very clear what's going on. And you don't need to make a decision today.
Step away for a while, as sandi said . Let W start to pursue YOU. It's her turn now to build some attraction back and make some deposits in your depleted Love Bank. If you find yourself re-attracted to her, you will start to feel love again. Same way it's worked with/for her. But don't deny her the dignity of her own struggle. Decide today you won't make a decision. Let's see if she will do the heavy-lifting for a while. If you could go either way, what do you stand to lose?
