WW-is there hope? Any advise from former WW's

[LANE777]

So I really never heard back but my sister and husband did. My W mom texted my brother in law asking if they could come to the cabin on those dates. He passed it on to my sister to handle. I told them its up to them. They decided not to respond. They know whats going on and are disrespecting my feelings for sure. So yesterday I was driving home and the W called and asked when I would be home so she could spend her time with the kids. Why wouldn't she text? no big deal but its seems she would normally avoid talking to me. The conversation was very short. So since she never replied to my text, I texted asking her if she wanted to talk about it. She replied,"There really isn't anything to talk about, sounds like its done, I told my mom we weren't doing it." my reply was "ok, i never heard back from you so was just wondering".
I called and asked my sister if they were still trying to reserve the cabin, she said she hadn't heard anything but would let me know if they did.
It seems to me the W is trying to get more and more distant from me. I am just trying to step back as far as I can right now. While I was gone, she came a got a lot more of her belongings from our house.
She spent a few hours with the kids and then they are home with me till Wed. I'm not sure when she plans to bring the papers for me to look over.
A few things really bothers me about this whole mess. For one, her family really doesn't know the depth of this. I'm sure shes told her siblings that we are seperated but leaving out the part that she is having an A. I so bad want them to know.
She still go around saying her and OM are just friends. She even told my oldest D that they are just friends. My d told her mom not to lie and that she knows whats going on. The other thing is her parents just enable her to live there for free and know she is seeing another man even though they don't agree with it. I feel my sitch is so pathetic at times and know we are way better than this.
I'm pretty sure her and OM are back on again, but not sure and right now I kinda care but really just disappointed in everything that's going on in my life right now. I know our M wasn't perfect but it def wasn't horrible. It wasn't bad enough for her to walk out of 17 years and 4 kids. Everyone that know about it are in total shock. They cant believe she is doing this. The only ones that are not in shock are probably the people she works with or her family members who don't know about the affair she's been hiding. I'm going to coast this week and avoid any contact at all. My mind is exhausted and it has made me physically exhausted as well. Better get back to work.
