Prematurely called divorce busted, worse now

[Orich]

OK, I get it, she might be having an EA. I still doubt it for a couple of reasons, but I admit it is a possibility.
apart from that, this is what confuses me, but kinda gives me hope: Our everyday interactions are barely different than before. We joke together, tell stories of our days to each other, etc. If she was just sticking around for the kids, why would she still get along well with me when they aren't around, or in bed sleeping at night? We had my family over on Saturday for father's day, and she cooked and cleaned, and put together a great day for my family. On Sunday, we went to her sister's house for fathers day with her family. She made sure I ate while she chased after the kids, looked into my eyes while talking to me with other people and even confirmed a camping trip for next month.
She now tells me she in fact will see a psychotherapist starting today. I'm not sure exactly what she wants to get out of it, whether or not it is for our marriage or just for her. Hopefully it is the former.
Am I missing something here? Does she really have feelings for me, just blocked by unresolved grief and other stress? Or is she actually basically cold in that she can truly feel nothing for me at all other than a good friend, I guess?
If there is the tiniest of possibilities that she can turn around and love me again, and we can be a normal family again, I can wait until the end of time. If there is no possibility, as painful as it would be, I would like to just move on and hope there is a possibility of finding someone else to share my life with. I really really hope it doesn't come to that.
