Living with a WAS/MLC husband...who does not care

[BlueSea]

Thank you LH and Steve, always looking for your posts on this thread!

He is being remorseful and repentant - he is reading books on how to help me heal, always coming forward with answers and being 100% transparent about everything. He is ready to talk about anything at anytime. With that said, there have been a lot of painful things that have come out:

-He did take her on a business trip to San Francisco and visit Napa Valley (on my birthday).
-She was trailing us on our RV trip down the Oregon coast during Memorial Day weekend.
-He finally told me her real name (I had it wrong), based on social media she was clearly smitten with him (he had said she was a 'guy' about it, and had no feelings invested) but she was invested in that relationship, and her posts show it.
-And other things that shouldn't matter but hurt nonetheless: 15 years younger, fully tattooed from head to toe literally, social media is all about sex, weird underground alternative lifestyle and available on escort sites (though H says he did not know that). Completely opposite type to me.
-He said she was really nice, I jabbed back, "a prostitute with a heart of gold" type eh?
-2 kids (almost the same age as ours) with 2 different fathers, and she gave them both up....just from what I see and read, clearly someone already with life issues. She has a few years left to peddle that overweight tattooed body, and then she will really be in a world of hurt. (sorry that is judge-y)
-Among the many posts of her naked or almost or in alternative costumes - she posted naked pics of her rubbing cake all over her, and eating it with caption of "You CAN have your cake and eat it too" around the same time that H and I had conversations at his WAS cake eating. GRR.

I know it doesn't matter - I know - BUT knowing is helping me to process and close the door, in a sense that the book has been read - I can put it down. I now know it all, and need to process all of it.

He is back. Its the H I remember. He is going to try. I think we have some hope to go the distance. I am in, but cautious. Any advice on this?
