Hi NYG, now this is just my take but I suspect your W became fearful of losing you. And things tailed off with OW, so she was dropped. From your positive reaction, your W has become reassured of your availability. However, she's also gone into a bit of a spin. Now she 'has you' - is that what she really wants?
I had a similar thing with my H - the 'friendships' he wanted to pursue were those with young, attractive, single or divorcing women. When I raised concerns, he said I was overreacting and he had female friends and enjoyed their company - blah, blah.
I would suggest drawing back a little. Let yourself become 'the pursued' again - without necessarily saying anything to your W.
Sorry there are some teething problems - but my understanding is - piecing never successfully happens without a rocky road along the way.
Take care xx
