Hi MissingHer2. Very sorry you are here but you have come to the right place.
First this...
The whole coming over to see the dogs thing does have me confused.
Mission accomplished on her part. Coming over to see the dogs is a page out of the wayward playbook and sends a couple of messages. First is that she may be doing just enough to keep you from filing for divorce like confuse you. This keeps you as security for plan B in case if plan A does not work out. Also sort of sends a message that "hey in the long run we can still be friends right. This way I don't have to look like the bad guy."
Also speculating here but I think this makes sense... She has to tell you to leave when she sees the dogs because her boyfriend will only give the ok for her to see the dogs if you're not there. Her AP (affair partner) may suspect that she's keeping you around as plan B.
Unfortunately I don't think you have a lot of options here as your WW has clearly left the marriage. You could go nuclear and expose the A as affairs cannot survive in the light of day.
Your WW's behavior is that of an addict at this point and her AP is her supply. That is who you are now dealing with. Expose the A and start to show your WW consequences.
Normally I would say wait to R or D until the situation is assessed. But since your WW has clearly left in your case I think you should file for D and get the ball rolling. Show her that you are not sticking around to be her plan B. Knock her off that fence if she's doing a bit of fence sitting here.
Also, gently and respectfully, get yourself tested for STDs. This is for your health. Too many times people come through here to find out they have something later. This should be a mandatory step for you.
You also need to start limiting your conversations with your WW about finances only. Start pushing on getting debt paid, get your own checking account and start separating finances. You don't want to be stuck holding any unnecessary bills at the end. With that, read up on the 180 and start using it right away. I will include some links here to help get you started.
You can find most of the abbreviations here in the upper left corner in the Healing Library. Please check that section out.
