Sound like you got some good advice here. You are a wonderful lady. And someday you can look back on this and it will be just a bad memory.
You have a lot of strength and bear a heavy load! As I found this is a good place to vent and get some advice. Feel free to come here and get things off your chest!
As I keep saying this is our H's journey and they have to travel it alone. Even if in your case he lives with you. It is plain he really doesn't love the OW, but is using here. Demons are fighting inside of him. All you can do is watch.
Sorry I'm not much help, but, you know you can count on my support!
