I wonder if it is lust you have with her. You got something from her you never had and now you want it all the time. I can see where you could be attracted to her and how you are in love.
She woke something up in you the other women did not. Not sure what to tell you. There are things you want and you should enjoy those things. If she is unwilling or unable maybe it's not the best situation for you. I think you both need to sit down privately and have a long talk.
