For what it's worth I think your XW is still interested in you. AN HOUR phone call is a LONG TIME. I would never talk to my X that long, and when he phones, even when we were dating, we would never talk for longer than about 15 minutes.
I personally wouldn't have allowed her to talk that long. For one, she may at a later date make out that you were prolonging the convo or breaking the RO and you have no way of disproving this. You need more of a barrier to protect yourself.
Secondly, you are not showing her the reality of her RO. If she's phoning and chatting for an hour right after she has got an RO, she obviously does not see the reality of what she has done or understand the concept of cause and effect.
Since she has persisted in that course of action and is keeping you out of the house, asserting you are pathologically controlling etc, I think you should show her these actions have consequences and next time she tries to bring herself into the convo or to prolong a discussion, I would point out 'XW, we have an RO. I have to go now.'
Thirdly, by engaging in these lengthy discussions with her and still being there whenever she wants, you are feeding her psychological dependency of you and allowing her to have an R with you without her actually putting anything back in or behaving in a reasonable manner.
In other words, she will never respect you and will always take you for granted if you let her treat you like that and then act as if nothing has happened afterwards.
Plus, if you're allowing her all this contact, she has no reason to come back to you because she gets all the friendship from you anyway, and sex was never a big thing to her so she'd probably be happy with that.
I'm sorry if this is a bit blunt but I'm saying it because I've been through the same with my X where he'd take me to court and then expect to date me 2 days later and I did it because I wanted to keep him, yet like that, he had no reason to come home, no reason to treat me better and he didn't have to miss the benefit of my friendship.
He have even said 'I can't respect someone who just gives in to everything I want.'
When I set boundaries and point out to him when he has treated me bad, when I withdraw from him and don't allow him contact if he has upset me, he will always come back, apologise and start trying to behave better.
I agree the past is the past, but not to the extent where you just forget everything she has done and become a doormat.
