really good signs! Anita makes a really good point about how you will start to look better in W's eyes than OM, because you're acting so great! And she talks so much to you, too- that comfort and sharing her innermost thoughts is an underlying key in an intimate R. So you're already at least halfway there. Of course OM should feel threatened- let's face it, you're the one with the real connection! What's also worked for me is doing stuff to help me appear more new, fresh, exciting to get those sparks happening. Like I am a fun 'single' person too, who happens to be living with my S. Once you've got a great underlying base of friendship, this kind of thing helps move it toward the next level.
