If you do go down the path of having female company, do it for you, not for her or to get a reaction

If its just as friends, fine, there is nothing wrong with it, that's for you to decide

But you have said that she ha acknowledged your changes, she sees them and likes them, so just maintain then!!
Time is your friend now, it's all about maintaining it

See it as a test of yourself, If you have changed for you, and you like the changes, do it for you, if she's not interested, guess what, you'll still be happy!!

It's strange but it is a win win decision!!
