I hate to say it Atlas, but I think this is the right decision as I've continued to watch your W exhibiting the "more of the same" behaviors she's shown since you came to this site. IMHO, she is definitely stringing you along, and it simply has to do with the recent outcome in court. Like I asked you when you first came back to the boards: do you think your W would've asked to work things out if the outcome in court fell in her favor? Methinks we both know the answer to that. Remember what she told you immediately following court -- about how she got "raped in court" and that now she's lost her H, family, and home -- ? I think the first part of that statement says a lot about her reasoning to continue stringing you along. She got her ass handed to her in court, and now she's trying to get you to reverse what happened that day. It's all about her, and I'm glad you're realizing that. If she really wanted to work on things with you, she wouldn't continue asking you to watch your S while she went out partying, continue not following through with plans, keep fence sitting, etc. And I'm not sure how you know that she's going out and being arm candy for this older guy, but that says a lot too. And are you saying she's escorting him, or being an escort in general? I guess either way, not something you want to invest your heart in.
Sorry if this comes across blunt, but from my POV, your W is playing with your heart in order to serve HER best interests, and your choice to move on and end this game of hers is the best thing you can do for you, and sadly, your S. At least at this time. She hasn't proven she's changed at all.
